Question

Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angles are described clockwise, from uppercase left. Where lines e and c intersect, the angles are: 1, 2, 4, 3. Where lines f and c intersect, the angles are 5, 6, 8, 7. Where lines e and d intersect, the angles are 9, 10, 12, 11. Where lines f and d intersect, the angles are 13, 14, 16, 15. Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100°

Answer 1

answer:

a

step-by-step explanation:

to find the intercepts, that is where the line crosses the x and y axes

• let x = 0, in the equation for y- intercept

• let y = 0, in the equation for x- intercept

x = 0 : - 15y = 60 ⇒ y = - 4 ← y- intercept

y = 0 : 3x = 60 ⇒ x = 20 ← x- intercept
