Answer:

The measures of the angles: m∠1 = 51°, m∠2 = 39°

Explanation:

In this type of question, you should substitute the measures of the angle by the given values and solve the equation to find x, then find the measure of each angle.

∵ m∠1 + m∠2 = 90°

∵ m∠1 = 3x°

∵ m∠2 = (x + 22)°

→ Substitute m∠1 by 3x° and m∠2 by (x + 22)° in the equation above

3x° + (x + 22)° = 90°

→ Add the like terms in the right side

∴ (3x + x) + 22 = 90

∴ 4x + 22 = 90

→ Subtract 22 from both sides

∴ 4x + 22 - 22 = 90 - 22

∴ 4x = 68

→ Divide both sides by 4 to find the value of x


(4x)/(4)=(68)/(4)

x = 17

→ Now substitute the value of x in each angle to find them

∵ m∠1 = 3x°

m∠1 = 3(17) = 51°

∵ m∠2 = (x + 22)°

m∠2 = (17 + 22) = 39°

The measures of the angles: m∠1 = 51°, m∠2 = 39°
