Extra Credit Quizizz: Trig Review #2

What is sin(S) expressed as a fraction in simplest form?

(a)  

Check off the appropriate options that would give the following trig ratio: 40/58

• sin(R)

• cos(R)

• tan(R)

• sin(S)

• cos(S)

Answer explanation

Because the hypotenuse H stays the same no matter which angle is given, the O and the A label switch, which means if using sin/cos, there are two possible ways to make a trig ratio. O/H using one angle and A/H using the other.

Check off the appropriate options that would give the following trig ratio: 42/40

• sin(R)

• cos(R)

• tan(R)

• sin(S)

• tan(S)

Answer explanation

Because the hypotenuse H stays the same no matter which angle is given, the O and the A label switch. If using tan, there is only one possible way to make a trig ratio O/A. A/O does not produce the same ratio from a different angle.

Select the appropriate equation to solve for x.

• sin(x) = 19/23

• cos(x) = 23/19

• tan(x) =19/23

• sin(23) = x/19

Malia sees a beautiful hot air balloon flying at a distance at a 76 degree angle of elevation. If the horizontal distance between her and the hot air balloon is 354 feet, find the height of the hot air balloon.

Which of the options best describe the diagram.

• 76 is the top angle, 354 is the hypotenuse side, x is the vertical side.

• 76 is the bottom angle, 354 is the hypotenuse side, x is the vertical side.

• 76 is the bottom angle, 354 is the horizontal side, x is the vertical side.

• 76 is the top angle, 354 is the vertical side, x is the horizontal side.
