Answer:
<em>∠I ≈ 53.13°</em>
<em />
Step-by-step explanation:
It can be seen from the figure that IP is perpendicular to KP
=> So that IPK is the right-angled triangle with angel IPK equal to 90°
In a right-angled triangle, there is a formula as following:
<em>+) sin of an acute angel = length of opposite side/ length of hypotenuse</em>
In triangle IPK, ∠I is an acute angel, its opposite side is KP.
The hypotenuse of triangle IPK is IK
So that, we have:
<em>+) sin ∠I = KP/ IK = 8/10 = 0.8 </em>
<em>=> ∠I ≈ 53.13°</em>

Step-by-step explanation:
Each multiple choice question would be 5 points. For Louann she got 14 of the questions correct so 5 x 14 = 70 and 70 + 24 would be 94. For Carla she got 16 of the questions correct so 5 x 16 = 80 and 80 + 14 = 94. You're answer would be 5, hopefully this helps :)
