Answer: D. 28
Step-by-step explanation:
The 3 interior angles of a triangle always add up to 180
Soooo:
95 + 57 = 152
180 - 152 = 28
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
Answer:
1029
Step-by-step explanation:
Volume= x 
x height = x 
x 21 = 1029
I hope it helps you!
It looks like you have to do distance formula. It's basically this:
D = 
(ignore the A, i dont know how to get rid of it sorry)
I would then plug in the points of A(1,7) and B(10,3).
D = 
Then I would get the square root of 4^2 + 9^2
= square root of 16 + 81
= square root of 97
So the length of AB would be the square root of 97
