Answer:
<h3>x = 12</h3>
Step-by-step explanation:
Given the triangle MNO which is extended through point O to point P, we are given the followings;
Interior angles;
∠MNO=(3x+11)
∠OMN=(2x+20)
Exterior angle;
∠NOP=(8x−5)
To find x, we will use the theorem, "The sum of the interior angles is equal to the exterior"
Hence;
3x+11+2x+20 = 8x - 5
5x + 31 = 8x - 5
Collect like terms;
5x - 8x = -5-31
-3x = -36
x = -36/-3
x = 12
Hence the value of x is 12
Answer:
X-3=Y
Step-by-step explanation:
-3-3=-6
1-3=-2
5-3=2
9-3=6
Answer:
27
Step-by-step explanation:
15x-31 = 9x+11
6x-31 = 11
6x = 42
x = 7
15x -31 + 9x + 11 + s = 180
15(7) -31 + 9(7) + 11 + s = 180
105 - 31 + 63 + 11 + s = 180
153 + s = 180
s = 27
