Question

angle A and Angle B are complementary angles if angle is equal to 7 degree + 4 x and angle b is equal to X + 3 degree which is a true statement
(a) angle A is acute
(b) angle A and a Angle B are 45 degree each
(C )angle A is obtuse
( d) the angle b is greater than angle A ​

Answer 1

Answer:

a) angle A is acute angle only

step by step explanation

angle A + angle B = 90⁰

7⁰ + 4x + x +3⁰ = 90⁰

10 + 5x = 90⁰

5x = 90⁰ - 10⁰

5x = 80⁰

x = 16⁰

therefore angle A = 7 + 4x

= 7 + 64 = 71⁰

angle B = x + 3 = 16 + 3 = 19⁰
