Question

major arc jl measures 300°. which describes triangle jlm?
right
obtuse
scalene
equilateral

Explanation:

Answer:

equilateral (First, find the measure of the minor arc JL: \( 360^\circ - 300^\circ = 60^\circ \). Since \( M \) is the center, \( MJ \) and \( ML \) are radii, so \( MJ = ML \). The central angle \( \angle JML \) is equal to the measure of arc JL, which is \( 60^\circ \). A triangle with two equal sides (radii) and a \( 60^\circ \) included angle is equilateral, so triangle JLM is equilateral.)
