Answer:

6841

Step-by-step explanation:

Use the Pythagorean Theorem equation a^2+b^2=c^2

Let 21 =a and 80 = b

We need to solve for c^2

Now plug in.

(21^2)+(80^2)=6841

Answer:

Solution given:

angle : 80°

hypotenuse:y=?

opposite=21

we have

Sin 80=[tex]\frac{opposite} {hypotenuse}=\frac{21}{y}[/tex]

doing crisscrossed multiplication

we get

y=[tex]\frac{21}{Sin 80°}[/tex]

y=21.32
