When the 2 sides of a triangle are equal ( in the figure shown both sides are 21) then the two bottom inside angles would aldo be equal to each other.

The three inside angles of a triangle need to equal 180 degrees.

Subtract the top angle from 180 and then divide by two:

180 - 38 = 142

X = 142 /2

X = 71 degrees.

Can someone help me find the volume of this shape?

ira [324]

Answer:

Step-by-step explanation:

To find volume you have to use the formula (length x width x height.)

So by looking at it you can see that it's 3 units long, 3 units in wide, and 2 units tall. Knowing that, you then plug in those numbers to the formula. That would be 3x3x2. Any calculator will work.
