Question

I need some help with this problem

Answer 1

For a 45-45-90 triangle if the sides rae x then the the hytponuse is x√2
(x is the missing side)

5. 10=x√2
10/√2=x
rationalize denom, times top and bottom by √2
10√2/2=x
5√2=x=XY

6. 12√2=YZ

7.
7√2=XZ

8.
7*2=14=XZ


for 30-60-90
the side oposite the 30 deg is x
side oposite 60 is x√3
side oposite right angle is 2x
hyptonuse is oposite right angle
20=2x
10=x=shorter leg
shorter leg is 10 units
the hyptonuse
