Answer:

Step-by-step explanation:

Sides AB and AC are equal

So,

3x - 5 = 7

+ 5 on both sides

3x = 12

divide both sides by 3

x = 4

Now take the 2x and plug in x for 4.

2(4) = 8

Final answer is 8.

The measure of the supplement of an angle is 84° less than the measure of the angle. Find the measures of the angles

babunello [35]

Let the measure of angle be 'x'

Since, the measure of the supplement of an angle is 84° less than the measure of the angle.

Therefore, measure of supplement of x = x - 84°

The measure of two supplementary angles is 180 degrees.

$x + x -84^\circ = 180^\circ$

$2x -84^\circ = 180^\circ$

$2x =84^\circ + 180^\circ$

$2x =264^\circ$

$x =132^\circ$

So, the measure of angle = $x =132^\circ$

Its supplement = x - 84° = 132° - 84°

= 48°

So, the measure of supplement of angle is 48 degrees.
