c. 65Ā°
step-by-step explanation:
we are given a triangle with two known angles, 62Ā° and 53Ā°, 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 + 62Ā° + 53Ā° = 180Ā°
solving to find the value of x:
x = 180 - (62 + 53) = 65Ā°
therefore, the value of x in this triangle is 65Ā°.
