If the measure of angle 3 is equal to (2x + 6)° and x = 7, which statements are true? Check all that apply. 3 lines intersect to form 6 angles. From top left, clockwise, the angles are 1 (90 degrees), 2, 3, 4, 5, 6.

The measure of angle 6 is 20°.

The measure of angle 5 is 70°.

The measure of angle 2 is 80°.

Angles 2 and 5 are complementary.

Angles 5 and 6 are supplementary.

Angles 1 and 4 are supplementary.
