Combine the following and write in standard form.
(7 + 5) + (-6 - 81)

without exponents its -75 since i thought those last 2 were exponents.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

pi x^2

step-by-step explanation:

pi times x squared
