Answer:
8p+7p+90 =180 (sum of three angles of triangles)
15p= 180-90
15p=90
p=90/15
p= 6
Step-by-step explanation:
p=6
triangles add up to 180 degrees, and a right angle =90 degrees.
from there, we can do 180-90=90 degrees then do 90/15=6. p =6
(we divide by 15 because 7+8=15)
to check, we see if all angles add up to 180.
7×6=42 8×6=48 right angle=90
42+48+90=180
b= 60
c=30
every triangle is equal to 180°
180°-90=90
b=90-60=30
the volume of a prism is v=ahh, where b is the base and h is the height. The base of the prism is a rectangle. Multiply the base by the height, and that is the volume.
p= 0.44 x 260
Hello!!!
That is the answer :D
