Find the value of x.
Please help

To find the value of X, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

4.) the angles are congruent, so they can be set to each other to determine the value of x.
14+6x=134
6x = 120
X=20

The angle would be equivalent to 180 (straight line) so,
134 +
6.) set the equation to 180 degrees (straight line)
36+[(x/3)+99]= 180
135 + x/3 = 180
x/3 = 45
X=45 x 3
X = 135

#2.) the angles are congruent, so again set the equation to each other and solve for x.
7x-4=87
7x=91
x = 91/7
x = 13

#4.) the sum is equal to 90 degrees (right angle)
81+(2x-51)=90
2x+30=90
2x=60
x=30

Hope this helps.

Im sorry but what on
