Question

if angle M and angle N are complementary angle and M (M)=( x +30)° what us the measure of the angle N​

Answer 1

Answer:

(y – 20)° and (y + 30)° are the measures of complementary angles. ∴ (y – 20) + (y + 30) = 90 ∴ y + y + 30 – 20 = 90 ∴ 2y+10 = 90 ∴ 2y = 90 – 10 ∴ 2y = 80 ∴ y =80/2 = 40 Measure of first angle = (y – 20)° = (40 – 20)° = 20° Measure of second angle = (y + 30)° = (40 + 30)° = 70° ∴ The measure of the two angles is 20° and 70°.Read more on Sarthaks.com - https://www.sarthaks.com/860478/y-20-and-y-30-are-the-measures-of-complementary-angles-find-the-measure-of-each-angle
