Answer:
Option A is the correct answer.
Explanation:
The given pyramid has 3 lateral triangular side as shown below.
Base of triangle = 12 unit
We need to find perpendicular.
By Pythagoras theorem we have
Perpendicular² = 10²-6²
Perpendicular = 8 unit
So area of 1 lateral triangle = 1/2 x Base x Perpendicular.
= 1/2 x 12 x 8 = 48 unit²
Area of lateral side = 3 x 48 = 144 unit²
Option A is the correct answer.
0=0
5=60
10=100
15=140
17=156
33=284
I think
hope I'm right but either 2 or 4 i can kinda go either way
-13 +3x +8 = 3x + (-5)
-9x + 15 - x -10 = -10 x + 5
The other two don't match
3+2•6/3
first you multiply the 2 and 6 on the top to get 12
so now it’s
3+12/3
now add the 12 and 3
15/3
now divide
so your answer is 5
