Answer:
x=30, <A=60, <C=30
Step-by-step explanation:
A triangle always has its total angles added up to 180 degrees, so we can set up the following equation:
90+2x+x=180
90+3x=180
3x=90
x=30
Since x=30, this means <C is 30 degrees. For <A, it's twice as much as <C, so 2*30=60.
So x=30, <A=60, <C=30
Hope this helped!

Answer:
x= 0, 1/2
Step-by-step explanation:
Cosα=x/L
x=Lcosα, we are told the ladder is 10ft and α=42.5 so
x=10cos42.5° ft
x≈7.37 ft (to nearest hundredth of a foot)
