I don’t understand this is there a longer question?
Answer:
20a³
Step-by-step explanation:
Simply multiply:
-5(-4) = 20
-a(-a)(a) = a²(a) = a³
20a³
The measure of length SV is 60 units
<h3>Isosceles Right Triangle</h3>
An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.
The above means that:

Substitute values for SV and ST

Subtract z from both sides

From the figure, we have:

Substitute 30 for z


Hence, the measure of length SV is 60 units

I think you meant to have more of a problem stated.
Basically, you use the Law of Sines when you have 2 angles but the length of only one side.
The formula for this law is
a / sine(A) = b / sine(B) = c / sine(C)
