In the figure below, angle y and angle x form vertical angles. angle y forms a straight line with the 80° angle and the 60° angle. write and solve an equation to determine the measure of angle x. (5 points)

40°

Step-by-step explanation:

The angles x and y are given to be vertical angles.

Now, angle y forms a straight line with the angles 80° and 60°.

Therefore, there forms a triangle, the sum of whose angles is 180°.

So, ∠y + 80° + 60° = 180°  

⇒ ∠y = 40°

Since, x and y are vertical angles, so ∠x = ∠y = 40° (Answer)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
