3)
= 3.17...
1^2 = 1
2^2 = 4
is between 1 and 2 to the power of 2

Since

, it follows that

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so
Answer:
only a is the right triangle
Step-by-step explanation:
only a is the right triangle because it satisfies the pythagorean theorem.
a.)

while b,
b.)

Hello from MrBillDoesMath!
Answer:
b = 28 degrees
Discussion:
In general,
sin (90 - @) = cos(@)
Set 90 [email protected] = 62 => @ = 28 so
sin (90-28) = sin(62) = cos(28) => b = 28
Thank you,
MrB
