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:

option A

Step-by-step explanation:

Angle A + Angle B = 90° ( complementery angle)

7 + 4x + x + 3 = 90

therefore x = 16°

Angel A =16.4 + 7 = 71°

hence Angle A is acuta angle
