Answer:
128
Step-by-step explanation:
The two angles form a straight line so they add to 180
2m+62 + 3m +143 = 180
Combine like terms
5m+205=180
Subtract 205 from each side
5m+205-205=180-205
5m = -25
Divide by 5
5m/5 = -25/5
m = -5
We want to find the angle so we substitute the value of m into the the formula for the angle.
< RBM =3m +143 = 3(-5) +143 = -15+143 =128
Itd be 50% hope this helps
Answer:
The answers is below in the picture.
Step-by-step explanation:
We first need to find the area of the big rectangle, and then find the area of the smaller square.
If we do:
Area of big rectangle - Area of square = Area of shaded region.
(x+10)(2x+5) - (x+1)(x+1) = Area of shaded region
