Answer:60
Step-by-step explanation:
Pythagorean's theorem gives us 100^2-80^2=b^2
Simplifying this we get:
10000-6400=b^2
3600=b^2
b=60

Answer:
∠4
Step-by-step explanation:
"Alternate" means the angle is on the other side of the transversal t. "Exterior" means it is on the outside of line e crossing the transversal. The alternate exterior angle to angle 8 is angle 4.
X= 19/12 which is 1.58 in decimal form
Answer:
XY = 18
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
10 XY = 180 ( divide both sides by 10 )
XY = 18
I would minus 2 from both sides of the equation so that it becomes:
