Answer:
x=50
Step-by-step explanation:
To find the angle on the bottom left you would subtract 180-149 and get 31.
Then you would add 31 and 99 to get 130.
Then subtract 180-130 to get x=50 because all triangles equal 180 if you add all of the angles together.
Answer:
1. 16x-188
2. 5x-90
Step-by-step explanation:
1.
9x-8+7x-y=180
y=9x-8+7x-180=16x-188
2.
2x-y+3x=90
y=5x-90
Answer:
4(x+x+1+x+2)=156, x=12
Step-by-step explanation:
let the numbers be x, x+1 and x+2.
Now,
4(x+x+1+x+2)=156
4(3x+3)=156
divide both side by 4
3x+3=156/4=39
subtract 3 from both sides
3x=39-3
3x=36
divide both sides by 3
x=36/3=12
x=12
Hence, the smallest of the integers is 12.

Answer:
The value of u are,
0.93, -12.93
Step-by-step explanation:
It is given an expression in variable u
(u + 6² + 4 = 52
<u>To find the solution of given expression</u>
(u + 6)·² + 4 = 52
(u + 6)² = 52 - 4
(u + 6)² = 48
u + 6 = √48
u + 6 = ±6.93
u = ±6.93 - 6
u = 6.93 - 6 or u = -6.93 - 6
u = 0.93 or u = -12.93
