If angle 1 and angle 2 are complementary angles and if the measures of angle 1 is 8 more than the measure of angle 2 determine t
babunello [35]

Answer:

41° and 49°

Step-by-step explanation:

Given:

Angle 1 and angle 2 are complementary angles.

The measures of angle 1 is 8 more than the measure of angle 2.

Question asked:

Determine the measures of angle 1 and 2.

Solution:

Let ∠1 = x

Then ∠2 = x+8   (given)

As we know that sum of complementary angles are 90° and here given that angle 1 and angle 2 are complementary angles which means,

∠1 + ∠2 = 90°

x+x+8=90°

2x +8=90°

Subtracting both sides by 8,

2x=90°-8

2x = 82°

Dividing both sides by 2,

x=41°

∠1 = x=41°

∠2 = x+8

∠2 = 41+8 = 49°

Therefore, the measures of angle 1 and 2 are 41° and 49°
