Answer:
a. 53
Step-by-step explanation:
The side with length 15 is opposite the right angle, so it is the hypotenuse of the right triangle.
For angle x, the side measuring 12 is the opposite leg.
Our 3 items of interest are: angle, opposite leg, hypotenuse.
The trig ratio that relates the opposite leg to the hypotenuse is the sine ratio.
sin x = opp/hyp
sin x = 12/15
sin x = 0.8
Now we take the inverse sine of 0.8 to find the measure of the angle.
x = sin^(-1) 0.8 = 53 deg
Answer:
C
Step-by-step explanation:
Volume = base * height.
The area of the base = base * height/2
That means the area of the triangular base is 8 * 5.1/2 = 20.4
The height is 9, so the volume is 20.4 * 9.
That means the volume is 183.6, which is C
Lets look at the information we have:-
$7.50 per hour
How many hours to earn $116.25?
To answer this we will divide. Lets do it:-
116.25 ÷ 7.50 = 15.5
15 and a half hours.
CHECK OUR WORK:-
15.5 × 7.50 = 116.25
We were RIGHT!!
So, to earn $116.25 when getting paid $7.50 per hour you would need to work for 15 and a half hours.
Hope I helped ya!!!
Positive because it’s going upwards towards the right.
