Answer:
Step-by-step explanation:
the longest length is always the hypotenuse
Use Pythagorean theorem
a^2+b^2=c^2
5^2+10^2=c^2
c=11.18
Note: if c=13 than it is a right triangle
since 11.18 not=13
not right triangle
Answer:
she spent 75%
Step-by-step explanation:
Answer:
x=2 AB=hypotenus(h) angle ACB is 90
BC=p angle CAB is 30 also angle of refrence
Step-by-step explanation:
sin[30]=p/h
(1/2)=x/4
2x=4
x=2
Answer:
3x + 30
Step-by-step explanation:

3x + 30 would be an equivalent expression.
Hope this helps.
