Answer:

x = 5

Step-by-step explanation:

9x + 3y + 4z = 24

9x + 3(9) + 4(-12) = 24

9x + 27 + (-48) = 24

9x + 27 - 48 = 24

9x - 21 = 24

9x = 24 + 21

9x = 45

x = 45 ÷ 9

x = 5

3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.

A side of the triangle below has been extended to form an exterior angle of 164". Find
Arada [10]

Given:

Measure of exterior angle = 164°

The measure of opposite interior angles are x° and 53°.

To find:

The value of x.

Solution:

According to the Exterior Angle Theorem, in a triangle the measure of an exterior angles is always equal to the sum of measures of two opposite interior angles.

Using Exterior Angle Theorem, we get

x^\circ+53^\circ=164^\circ

x^\circ=164^\circ-53^\circ

x^\circ=111^\circ

x=111

Therefore, the value of x is 111.
