find each angle measure in the regular polygon

a. 128 4/7°
b. 108°
c. 150°
d. 120°

120°

Step-by-step explanation:

If you draw lines to the middle of the hexagon, you will get 6 equilateral triangles. Each angles in that triangle is 60°, and 60° + 60° is 120°.

120 degrees

Step-by-step explanation:

A hexagon has a sum of 720 degrees and divide that by 6 because you have 6 angles and you get 120 degrees

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

your answer is -9
