The surface area of this prims is found by adding the area of all the faces. To find the area of the rectangles the formula is length times width, and to find area of a triangle the formula it is length times width divided by two.
Answer:
d = -20
Step-by-step explanation:
Simply subtract the 1st 2 numbers together:
d = 5 - (-15) = -20
Constructing an a circle inscribed in a triangle involves these steps:
i) Draw 2 (or 3) of the angle bisectors. Their point of intersection is the center of the inscribed circle, or the incenter. Let's denote this point by O
ii) Draw a perpendicular line segment from the incenter to one of the sides. Let the intersection of the perpendicular from O and the side be T.
iii) Draw a circle with center the incenter, and radius the distance OT.
Answer: B) Only perpendicular bisectors are not involved.
Answer:
B
Step-by-step explanation:
check the answer,4 square=16,
4.5 square=20.25,
5 square=25
20.25<24<25,
so 4.5<square root of 24<5
