Question

∠1 ​and ∠2 are supplementary angles.

Answer 1

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve ~

As given in the question, the two angles are supplementary Angle pair.

According to that, the sum of measures of those angles will be equal to 180°

$\qquad \sf \dashrightarrow \: (2x + 4) \degree + 124 \degree = 180 \degree$

$\qquad \sf \dashrightarrow \: (2x + 4) \degree = 180 \degree - 124 \degree$

$\qquad \sf \dashrightarrow \: (2x + 4) \degree = 56 \degree$

$\qquad \sf \dashrightarrow \: 2x = 56 \degree - 4 \degree$

$\qquad \sf \dashrightarrow \: 2x = 52 \degree$

$\qquad \sf \dashrightarrow \: x = 52 \degree \div 2$

$\qquad \sf \dashrightarrow \: x = 26 \degree$
