True or False, the below is a right triangle: a = 14, b = 16, c =18
plug the equation into the formula a2+b2=c2
If the equation is true, it's a right triangle. If the equation is false, it is not.
A 15 foot ladder is leaning against a wall. The foot of the ladder is 7 feet from the wall. How high up the wall is the ladder? Round to the nearest tenth if necessary.
This triangle is missing a leg.
A=7
b=?
C= 15
Step 1: Use the formula the c2 - a2 = b2
step 2: Take the square root of your answer to solve for b.
How far off the ground is the top of the ladder? (Round your answer to the nearest tenth)
This triangle is missing a leg.
a=4
b=x
c=11
Step 1: Plug your variables into the missing leg formula c2 - a2 = b2
step 2: Take the square root of your answer to solve for b.
