I believe that the answer will be A
Answer:
168 square inches
Step-by-step explanation:
Assuming these are the dimensions of a rectangular prism, then the surface area is given by
TSA=2(lw+lh+wh)
We substitute the dimensions into the formula to obtain:
TSA=2(2*9+2*6+9*6)
We simplify to get:
TSA=2(18+12+54)
TSA=2(84)
TSA=168 square inches
Answer:
B
Step-by-step explanation:
For the three rectangles:
30x17=510
30x10=300
30x21=630
REMEMBER: the formula for solving triangles are Area = 1/2 base x height
For the 2 triangles:
1/2x21x8 = 84
And since there are 2 triangles that are both the exact same, you do 84x2, which equals 168
Finally, you add all the numbers together:
510+300+630+168 = 1,608
Which looks like is letter B on your paper
58 degrees
When does the square inside the angle that means it is a right angle and a right angle is 98° So all you need to do is 90-32
transitive propery, it states the a = b and b = c, then a = c
