Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
i will it means full combo so look at it closely it might be a or b that would be my guess i hoped i helped
The three integers are: 12, 13, and 14
12+13=25
25+14=39
Answer:
307cm²
Step-by-step explanation:
This is a composite firgue so we need to split the two shapes, then find the area of both.
find the area of the rectangle
A=b*h
A=18*10
A=180
then find the area of the semicircle
A=1/2Pi*r²
A=1/2Pi*81
A=127.75 (We need to find the radius of the semicircle then square it)
then add the two areas 180+127.75=307.75
find the closet unit its
307cm²
