Answer:
b = 55°
Step-by-step explanation:
Angles around a point will always add up to 360°
Therefore, we can write an expression where we sum the 3 angles given and equate them to 360°:
(b - 15) + 3b + (2b + 45) = 360
eliminate the brackets and collect like terms:
b + 3b + 2b - 15 + 45 = 360
Combine like terms:
6b + 30 = 360
subtract 30 from both sides:
6b = 330
divide both sides by 6:
6b ÷ 6 = 330 ÷ 6
⇒ b = 55
Answer:
(C) 90 
Step-by-step explanation:
The figure is a combination of two parallelograms. So, to find the area of the whole figure, all you have to do is find the area of each parallelogram separately (they happen to be the same in this problem) and then add them up. The formula for the area of a parallelogram is <u>A = base*height</u>. In each parallelogram, the base is 15 in., and the height is 3 in. Therefore, the area of each parallelogram is 45
and the area of the whole figure is 90
.
Hope this helps :)
