Answer:

Answer → 63°

Step-by-step explanation:

» m<3 and m<4 are supplementary angles.

☑ Supplementary angles are angles that measure up to 180°

${ \tt{m \angle 3 + m \angle 4 = 180 \degree}} \\ { \tt{117 \degree + m \angle 4 = 180 \degree}} \\ { \tt{m \angle 4 = 180 \degree - 117 \degree}} \\ { \tt{m \angle 4 = 63 \degree}}$

The product of a number and -7 amounts to seven times the sum of that number and 20. Find the number.

MA_775_DIABLO [31]

Answer: -10

Step-by-step explanation:

If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
