Answer:144
Step-by-step explanation:v=l•w•h
Length= 12cm
Width=2cm
Height=6cm
Multiply them to get the volume.
V=144
Perimeter of the new triangle is 576 ft
Step-by-step explanation:
- Step 1: Given the perimeter of the right triangle = 72 ft. Find new perimeter.
Perimeter of the triangle = sum of the sides = a + b + c = 72
Each side is multiplied by 8, so new sides are 8a, 8b, 8c
⇒ New perimeter = 8a + 8b + 8c = 8(a + b + c) = 8 × 72 = 576 ft
Answer:
x = 7
Step-by-step explanation:
Given the base of the triangle is 6 and the line dividing the triangle is x. To get x divide the triangle into two equal halves. When you do so,you’ll have a right triangle with x as the opposite , 8 as the hypotenuse and the adjacent as 3.
Using Pythagoras theorem, we have
8^2 = x^2 + 3^2
8 x 8 = x^2 + 3 x 3
64 = x^2 + 9
Subtract 9 from both sides
64 - 9 = x^2 + 9 - 9
55 = x^2
X^2 = 55
x = squared root of 55
x = 7.4
x = 7
