Solve the following equation: -3x + 10 = 21 * 1 point
x = 11/3
x = -11/3
x = 16/3
x = -16/3
x = 3
x = -3
x = 17
x = -17

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°.
