Isosceles triangle scalene triangle and equaliteral triangle
If you have a unit circle, it means that you have a circle of radius r = 1 unit. So if we consider the scalene triangle of the figure, its vertical side is the sine of the theta angle and its horizontal side is the cosine of the theta angle. Then to find the hypotenuse of the triangle you use the Pythagorean theorem, thus relating the sine and cosine measures. I attach the solution.
First, distribute 8
8s+24=72
Now, isolate the variable with inverse operations
subtract 24 from both sides
8s=48
Divide by 8 on both sides
s=6
Answer:
c 17
Step-by-step explanation:
because if you subtract 2 from 8 you would get 6,
6 times 2 is 12
add 5 to 12 and you get 17
