Hi PLEAZE HELP I DON'T KNOW WHAT TO DO (will give brainliest for best answer)

b) What is the sum of the exterior angles of the equilateral triangle ∠M + ∠R + ∠X? Explain your reasoning.
(image below)

360

Step-by-step explanation:

We know, each angle of an equilateral tringle is 60 degrees

For each angle, exterior angle = 180 - 60 = 120 degrees

So, sum of exterior angles = 120 + 120 + 120 = 360 degrees

[If there's any problem with the solution, please inform me]

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
