(9^2)+(22^2)=x^2
81+484=x^2
565=x^2
x is approximately 24 units
Answer:
B
Step-by-step explanation:
Answer:
11 %
Step-by-step explanation:
1 to 11 is < 12
P (<12) = 11/100 = 11%
Answer:
Lateral surface area is the area of the sides, not including the base and top area, while total surface area is the entire surface area (including sides, base, and top).
Answer:
- 
Step-by-step explanation:
Using the addition formula for cosine
cos(A + B) = cosAcosB - sinAsinB
Given sin A = -
=
and in fourth quadrant, then
the triangle is a 7 - 24- 25 right triangle with adjacent side 24
In fourth quadrant cosine ratio is positive , thus
cos A =
= 
------------------------------------------------------------------
Given sin B = -
=
and in third quadrant, then
the triangle is a 5- 12- 13 right triangle with adjacent side 5
In third quadrant cosine ratio is negative, thus
cos B =
= - 
Thus
cosAcosB - sinAsinB
= (
× -
) - (-
× -
)
= -
- 
= -
