Answer:

34.64 cm

Step-by-step explanation:

sin 60 = \frac{x}{40}

sin 60 (40) = x

34.64 = x

equilateral triangles have 60° angles.

sin Ф = \frac{opposite}{hypotenuse}

hypotenuse is 40. All sides are 40.

x = opposite or height of triangle.

Since the lines are perfectly straight, we can assume that each line in an arc is 180 degrees. since it gives us 43 degrees for the angle next to z, we just need to subtract 43 from 180. this gives you the answer 137 degrees.

137 degrees is your answer
