The side length of the square is 2*((8/2)^.5) = 4cm
The area is 4^2 = 16 cm

See the attached picture. The parts labeled a and b are both the same length since this is a square. And each of them is half of the side length of the square. We can find the length of a and b using the Pythagorean theorem because the 8cm is a hypotenuse of a right triangle. So we find a, and multiply by 2 to get the square side length. Then we square that to get the square area.

m∠RSU=(5x+7)° and m∠UST=(9x−1)°. If ∠RSU and ∠UST are complementary, what is the measure of each angle?
ArbitrLikvidat [17]

Answer:

37° and 53° respectively.

Step-by-step explanation:

We need to know that the angles are complementtary if ∠RSU + ∠UST = 90°. Then,

5x+7 + 9x-1 = 90

5x + 9x +7 -1 = 90

14x +6 = 90

14x = 90 - 6

14x = 84

x = 84/14

x = 6.

Then, the angle ∠RSU has measure 5(6)+ 7 = 30+7 = 37, and the angle ∠UST has measure 9(6) - 1 = 54-1 = 53.
