Answer:
A: 40 degrees
Step-by-step explanation:
Since every triangle is 180 degrees, you can start off by subtracting 50 from 180 since that side does not contain a y for you to solve.
Since the other two sides do have a y in them, you would set 130 degrees equal to y+10 and 2y:
130=y+10+2y
Then you would isolate the y's by subtracting 10, and you would add y and 2y together to get:
120=3y
Finally, you would divide 120 by 3 to get your answer, 40=y.
Hope this helps!
The Surface area of the figure is 520 square centimeters
<h3 /><h3>How to calculate the surface area of a figure</h3>
The figure is made up of rectangular prisms
The formula for calculating the surface area of rectangular prism is expressed as:
SA = 2(lw + wh + lh)
l is the length
w is the width
h is the height
Surface area of the figure = 2(2(8) + 2(14) + 8(14)) + 2(6(8) + 6(4) + 8(4))
Surface area of the figure = 2(16+28+112) + 2(48 + 24+32)
Surface area of the figure = 312 + 208
Surface area of the figure = 520 square centimeters
Hence the Surface area of the figure is 520 square centimeters
