Answer:
I would say B.
Step-by-step explanation:
Perpendicular lines meet at a right angle.
1057 is not prime. It can be divisible by 7 or 151. In the future, you can test each of the numbers up to dividing by 13. After that, it's unlikely that they'll be prime. :D

Answer:
3
Step-by-step explanation:
15+ _ x 5
15 divided by 5 = 3
3 x 5= 15
Answer: √117
Step-by-step explanation:
Since no diagram present, am assuming hypotenuse AB and right angle C. Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.
a^2 + b^2 = 22^2 (Pythagorean)
Using Pythag on two smaller triangles,
x^2 + 13^2 = a^2
x^2 + 9^2 = b^2
Substituting in first equation,
x^2 + 13^2 + x^2 + 9^2 = 22^2
x^2 = 117, so x = √117
