PLS HELP ASAP Which angle measures would make a triangle with three equal side lengths?
40°, 40°, and 1100
65°, 65°, and 65°
60°, 60°, and 60°
45°, 45°, and 90°

60°, 60°, and 60°

Step-by-step explanation:

A triangle with three equal side lengths is called and equilateral triangle. If the sides of an equilateral triangle are all the same, then the angles will be as well.

All triangles have a sum of 180°. This means that if you add up the the measures off all three angles, it will be 180°.

So, for equilateral triangles, you can divide the total number of degrees, (180), by the number of sides, (3).

180/3 = 60

So, each angle on an equilateral triangle has a measure of 60°

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
