Question

In ΔABC, m ∠B = n degrees, m ∠A = 2n + 1°, and m ∠C = n + 7°. Find the measures of all three angles. m ∠A = ° m ∠B = ° m ∠C = °

Answer 1

50 degrees

Explanation:

all three angles in a triangle add up to 180

subtract 7 and 1 from 180 getting 172

there are four n's so divide 172 by three and you get 43 degrees

plug that number into the equation for c which gives you 43+7 and you get 50
