Answer:

\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}

\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}

       m \angle 2=\boxed{33}\:^{\circ}

Step-by-step explanation:

From inspection of the given diagram:

  • m \angle 1=(3x)^{\circ}
  • m \angle 2=(x+14)^{\circ}

<h3><u>Part (a)</u></h3>

A right angle is 90° and is represented by the ∟ symbol.

To find x, <u>equal</u> the sum of the angles to 90° and solve for x:

\implies m \angle 1+m\angle2=90^{\circ}

\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}

\implies 3x+x+14=90

\implies 4x+14=90

\implies 4x+14-14=90-14

\implies 4x=76

\implies 4x \div 4=76 \div 4

\implies x=19

<h3><u>Part (b)</u></h3>

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}

\implies m \angle 2=(19+14)^{\circ}=33^{\circ}

Answer:

Equation: \sf 3x + x + 14 = 90

m∠1 = 57°

m∠2 = 33°

Explanation:

A right angle triangle has 90° angle measure.

Here:

m∠1 + m∠2 = 90°

(a)

Substitute given values:

(3x) + (x + 14) = 90

<u>simplify</u>

4x = 90 - 14

<u>evaluate</u>

4x = 76

<u>divide both sides by 4</u>

x = 19

(b)

m∠1 = 3x = 3(19) = 57°

m∠2 = x + 14 = 19 + 14 = 33°
