In the figure below, lines A and B are parallel. Find the m∠5 if m∠1 = 75° and m∠3 = 40°

Angle 5 is 75 degrees

Step-by-step explanation:

angle 1 is congruent to angle 5

so angle 5 is also 75 degrees.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
