She worked the night shift as a waitress at Hap's Diner. Her body was found, wrapped in plastic, in Wind River. She died from "repeated blows to the back of the head by a blunt obtuse-angled object," according to FBI Special Agent Sam Stanley. The murderer took her ring, which was adorned with a symbol used late in the series in conjunction with the Black Lodge.

Chevrons are used in group theory to write group presentations, and to denote the subgroup generated by a collection of elements. Note that obtuse angled chevrons are not always (and even not by all users) distinguished from a pair of less-than and greater-than signs <>, which are sometimes used as a typographic approximation of chevrons. In group theory and ring theory, brackets denote the commutator. In group theory, the commutator is commonly defined as .

Saint James Cavalier () is a 16th-century cavalier in Valletta, Malta, which was built by the Order of St John. It overlooks St James' Bastion, a large obtuse-angled bastion forming part of the Valletta Land Front. St James was one of nine planned cavaliers in the city, although eventually only two were built, the other one being the identical Saint John's Cavalier. It was designed by the Italian military engineer Francesco Laparelli, while its construction was overseen by his Maltese assistant Girolamo Cassar.

The wingspan is 17–18 mm. The forewings are snow white with bright orange markings, partially blackish edged. The costal edge is blackish towards the base and there is a moderate streak immediately beneath the costa from the base to the costa before the apex. A subdorsal somewhat irregular streak is found from the base almost to the anal angle and there is a transverse streak from two-thirds of the subcostal streak to the middle of the subdorsal, forming an obtuse-angled zigzag in the middle.

In the sinus-area there are very faint traces of dense spiral texture . Just above the shoulder two or three small close-set furrows appear, and from the shoulder down to the point of the shell the surface is scored with shallow, crimped, rounded little furrows, which are much narrower than the flat intervals which part them but become stronger and closer toward the point of the shell. Below the middle of the whorls there is an obtuse angled keel forming the edge of the shoulder. The colour of the shell is, spire under a pale, membranaceous, glossy, chestnut epidermis.

As P is constrained to lie within ABC, by the dogleg rule the length of this path exceeds AC+AF = d(A). Therefore, d(A) < d(P) for all P є Δ, P ≠ A. Now allow P to range outside Δ. From above a point P' є Ω exists such that d(P') < d(P) and as d(A) ≤ d (P') it follows that d(A) < d(P) for all P outside Δ. Thus d(A) < d(P) for all P ≠ A which means that A is the Fermat point of Δ. In other words, the Fermat point lies at the obtuse-angled vertex. Case 2.

The wingspan is 16–20 mm. The forewings are snow white with a moderate orange streak immediately beneath the costa from the base to the costa near the apex, sometimes obsolete beyond two-thirds. There is a rather broad orange streak along the inner margin to the anal angle, becoming suddenly subdorsal on the basal fourth and not quite reaching the base, usually more or less wholly suffused with dark fuscous, posteriorly attenuated. There is a transverse orange streak suffused with dark fuscous, from the subcostal streak at three-fifths to the middle of the dorsal streak, forming an obtuse-angled zigzag in the middle, sometimes interrupted or wholly absent.

The bluntnose stingray or Say's stingray (Dasyatis say, often misspelled sayi) is a species of stingray in the family Dasyatidae, native to the coastal waters of the western Atlantic Ocean from the U.S. state of Massachusetts to Venezuela. It is a bottom-dwelling species that prefers sandy or muddy habitats deep, and is migratory in the northern portion of its range. Typically growing to across, the bluntnose stingray is characterized by a rhomboid pectoral fin disc with broadly rounded outer corners and an obtuse- angled snout. It has a whip-like tail with both an upper keel and a lower fin fold, and a line of small tubercles along the middle of its back.
