Answer:
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement, and vice versa.
sin ∠QOP = cos ∠ROQ
cos ∠ROQ = sin ∠QOP
Answer:
C.)-5
Step-by-step explanation:
y2-y1/x2-x1
(-9,6) (-6,-9)
-9-6=-15
-6-(-9)=3
-15/3=-5
First compute the area of the square like this:

There is two semi circles here, so the sum of the two white
spaces equate the area of a circle.
the radius of the circle is 9/2.
So compute the area of the like this:

And the area of the shaded region is the area of the square minus
the area of the two semi circles, like this:

We are done.
Answer:b,A,D
Step-by-step explanation:
Answer:
c. 15 feet
Step-by-step explanation:
hypotenuse (h) = 25 feet
perpendicular (p) = 20 feet
base (b) = ?
we know by using Pythagoras theorem
b = 
= 
=
= 15 feet
hope it helps : )
