Step-by-step explanation:
area = ( base 1 + base 2 ) ÷ 2 x height
50 = ( 10 + 15) ÷2 x height
50 ÷ 12.5 = height
height = 4
Answer:
x = 18
18√2
Step-by-step explanation:
This is a special right triangle with angle measures 45° 45° 90°
in this special triangle the side lengths are expressed as a, a, and a√2
So x = a and x = 18
r = a√2 and r = 18√2
The slope is equal to 5/2.
Answer:
surface area = 136 m^2
Step-by-step explanation:
The prism has 5 faces.
Faces 1 and 2: The front and back faces are two congruent triangles with base 6 m and height 4 m.
Face 3: The bottom face is a rectangle with length 7 m and width 6 m.
Faces 4 and 5: The left and right inclined faces are two congruent rectangles with length 7 m and width 5 m.
area = area of faces 1 and 2 + area of face 3 + area of faces 4 and 5
area of triangle = bh/2
area of rectangle = LW
area = 2 * 6 m * 4 m / 2 + 7 m * 6 m + 2 * 7 m * 5 m
area = 24 m^2 + 42 m^2 + 70 m^2
area = 136 m^2
Answer: surface area = 136 m^2
The question is incomplete. However, the equation representing the information above is;
45x+50y=2500
