13. which equation has no solution? (1 point)a. 5v + 3 = 5v – 5 b. 2x – 4 = 2x + 7 – x c. 2y + 5 – y = 2y – 3(y – 6) d. 7z + 9 = –7z – 6

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°.
