One base angle of an isosceles triangle is 63.5. What is the measure of the vertex angle?

Answer:

4x-20 is the same as x+x+x+x-20

Answer:

3

Step-by-step explanation:

We can say that a zero or root, is a point that intercepts the x-line. In this case there are 3 points that intercepts the x-line.

(-2.8,0); (1,0); and (7,0)

Answer:

(3V)/A = h

Step-by-step explanation:

V = 1/3 Ah

Solve the literal equation using inverse operations;

V = 1/3 Ah

*3    *3

3V = Ah

/A     /A

(3V)/A  = h

Answer:

Answer is below

Step-by-step explanation:

Subtract 2x from both sides.

Subtract 15 from both sides.

Divide both sides by -1.

So therefore your answer is 15
