In △ABC, ∡A is 2 more than twice ∡B, and ∡C is 7 less than twice ∡B. What is the measure of each angle in △ABC?

a = 4 b

c = 2b-7

b                               summed = 180

 

 

 

4b       +      2b-7       + b   = 180      solve for b      then a = 4b      and   c = 2b-7

It's not 4b!!!

 

(2B + 2) + B + (2B - 7) = 180            B = 37

 

∠A = 76º

∠B = 37º

∠C = 67º
