Option A. 56°

Step-by-step explanation:

In the given diagram, the measure of angle 8 is 124° and ∠2 is 84°.

We have to find the measure of angle 7.

Since angle 7 and angle 8 are complementary angles (sum of angles on a line is equal to 180°)

m∠7 + m∠8 = 180°

angle 7 = 180° - m∠8

∠ 7 = 180° - 124° = 56°

Therefore, option A. 56° is the correct option.

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°.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
