Math Problem Statement

∠1 and ∠2 are complementary angles. If m∠1 = (2x - 26)° and m∠2 = (4x - 28)°, then find the measure of ∠2.

Solution

The problem states that ∠1 and ∠2 are complementary angles, meaning their measures sum to 90°. We are given:

  • m∠1 = (2x - 26)°
  • m∠2 = (4x - 28)°

Since complementary angles add up to 90°, we can set up the equation:

(2x26)+(4x28)=90(2x - 26) + (4x - 28) = 90

Now, let's solve for xx and then substitute the value of xx into the expression for m∠2 to find its measure. I'll solve this step by step.

Solving the equation:

(2x26)+(4x28)=90(2x - 26) + (4x - 28) = 90 Combine like terms: 6x54=906x - 54 = 90 Add 54 to both sides: 6x=1446x = 144 Divide both sides by 6: x=24x = 24

Finding the measure of ∠2:

Substitute x=24x = 24 into the expression for m∠2: m2=4x28=4(24)28=9628=68°m∠2 = 4x - 28 = 4(24) - 28 = 96 - 28 = 68°

Thus, the measure of ∠2 is 68\boxed{68^\circ}.
