Is this multiple chose? if so I would like to see the answers. But just using my brain, I would say, 5, or 7.
It's the identity equation so
421875 cm because you take the 75 and square it to the 3rd power
Answer:
1
Step-by-step explanation:
There is an important trig identity which you must know: (sin x)^2 + (cos x)^2 = 1.
Therefore, sin^2(20°)+cos^2(20°) = 1
8x + 5x + 5x = 180
18x = 180
x = 10
<span>the measure of the vertex angle = 8x = 8*10 = 80</span>°
