Two parallel lines are cut by a transversal. What is the measure of <7?

A. 57°

Step-by-step explanation:

Same side exterior angles are supplementary

∠ 1 + ∠7 = 180°

123° + ∠7 = 180°

-123°              -123°

∠7 = 57°

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
