Answer:
x = 20
Step-by-step explanation:
angle m<3 + angle m<5 = 180° because these angles are supplementary
5x + 10 + 3x + 10 = 180° add like terms
8x + 20 = 180
8x = 160 divide both sides by 8
See attached graph: v is on the y-axis and t is on the x-axis
2.7 cm per second. Because it’s 161 divided by 60
