For the bicycle frame shown below, the angle that the horizontal cross bar mix with the sea support is 12° less than twice the angle at the steering column. The angle at the pedal gear is 30° more than the angle at the steering column. Find these three angle measures

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

because 1.2 isnt half of 6 duh

i believe the answer is d.

hope it you! : d

goog may be able to you find that answer
