Answer:
Perimeter of triangle =40 feet
Step-by-step explanation:
Given:
Lengths of edges of triangle:
feet
feet
feet
Perimeter of the triangle= Sum of all sides = 
feet
On simplifying by adding like terms:
Perimeter of triangle = 
feet
Given 
∴ Perimeter of triangle = 
= 40 feet
Answer:
208 ft^3
Step-by-step explanation:
Let the plane through the 4 ft X 4ft square at the top of the figure break the figure into 2 boxes, one has dimensions (8-7) by 3 by 4 = 1ft X 3ft X 4ft, and the other has dimensions 7 by 7 by 4 = 7ft X 7ft X 4ft.
They have volumes of (1)(3)(4) = 12 ft^3, and (7)(7)(4) = 196 ft^3, respectively, so the total volume = 12 + 196 = 208 ft^3, the answer.
88.4*10^3 is = 88.4*10*10*10 =88400
Hope this helps! Any questions please just ask! Thank you!
Hope this will help you .
answer is 68
given than 2 sides are equal therefor 2 angles are also equal ,
so, angle 1 + angle2 + angleX = 180 [ASP]
2angle1 + angle X = 180
angle x = 150 - [56][2]
angle x = 180-112
ANGLE x = 68 DEGREE
