Answer:
Area of ΔABC = 144 ft^2
Step-by-step explanation:
ΔABC is 45 45 90 right triangle
Ratio of leg (AC, BC) : hypo (AB) = x : x√2
Given hypo AB = 24 so AC = BC = 12√2
Area of ABC = 1/2 bh
= 1/2 ( 12√2)( 12√2)
= 1/2(144 * 2)
= 144 ft^2
Answer:6 by 9
I was stuck on thus question too for a while but then I went back and figured everything.
Answer:
P = 8.9k
Step-by-step explanation:
To find the perimeter, you need to add all three sides of the triangle.
P = (1.8k - 5) + (3.5 + 6.1k) + (k + 1.5)
Because you are adding all three expressions, you can remove the parentheses.
P = 1.8k - 5 + 3.5 + 6.1k + k + 1.5
Now you want to combine the variable (k).
P = (1.8k + 6.1k + k) - 5 + 3.5 + 1.5
P = (8.9k) - 5 + 3.5 + 1.5
Now you want to combine the constants.
P = (8.9k) - 0
You are left with:
P = 8.9k
