Question

In triangle​ ABC, the measure of angle B is 44degrees more than three times the measure of angle A. The measure of angle C is 61degrees more than the measure of angle A. Find the measure of each angle.

Answer 1

Answer:

m<A =15, m<B=89, m<C=76

Step-by-step explanation:

A = x

B = 44 + 3x

C = x+61

44 + 3x + x + x + 61 = 180

(you get 5x because you're adding the additional actual value of A to the equation)

now you gotta mush this together

5x + 105 = 180

and now subtract

5x = 75

then divide

x = 15

Great! we found the value of angle A!

now lets plug this in for x in the formulas up top!

B = 44 + 3(15)

B = 44 + 45

B = 89

Yayyyy we're almost done!

C = (15) + 61

C = 76

That's it! that's the value of each angle!

you can check your work by adding the three numbers together to get 180

so lets see

15 + 89 + 76 =
