1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
Given: 7r+3r-8=8+2r
Simplify: 10r-8=8+2r
Addition: add 8 to each side: 10r=16+2r
Subtraction: Take 2r from each side: 8r=16
Division: Divide each side by 8 for answer: r=2
Answer: r=2
Answer:
Step-by-step explanation:
Pyramid height should be 14
Base area should be 14*14(196)
So, Base area is 196
1. Multiply the Base area by the height of the pyramid:
196*14=2744
2. Divide the number above by 3:
2744/3=914.7
