The two angles are complementary because the angles are both a part of a right angle (a 90-degree angle), so they will both add up to 90 degrees, making them complementary.
Hope this helps!
Answer:
Step-by-step explanation:
Before, we had b bones. Now, we have four more, so .
No need to guess, just math!
x + y = 85, so x = 85 - y
Let’s substitute this in the second equation
y = 2(85 - y) + 4
y= 170 - 2y + 4
3y = 174
y = 58
x = 85 - 58 = 27

Answer:
B
Step-by-step explanation:
cosA = 
= 
= 
cosC = 
= 
sinC = 
= =
tanC = 
= 
= 
Then
cosA = sinC → B
Volume = Ah
where:
A is area of base
h is perpendicular height
