Answer:

1464 inch²

Step-by-step explanation:

given first prism sides: length - 10 width - 10 height - 10

given second prism sides: length - 12 width - 12 height - 12

using the formula below:

for the first prism:

2(10*10+10*10+10*10)

600 inch²

for the second prism:

2(12*12+12*12+12*12)

864 inch²

So total surface area is (864 inch² + 600 inch²) =1464 inch²

Triangles and angles<br> Pls help
AleksandrR [38]

Answer:

The two bottom angles of this triangle are both represented by the same variable, in this case, an x. This means, that both of the bottom angles are equal to each other.

So we have:

32 + x + x = 180 (since the TOTAL angles of a triangle adds up to 180)

32 + 2x = 180 (combine the 2 x's together)

2x = 148 (subtract a 32 from both sides)

x = 74

Let me know if this helps!
