Step-by-step explanation:
ANSWER
The correct answer is 19.1
EXPLANATION
The perimeter of triangle OQR is the sum of the distance around the triangle.
Thus,

We can observe that two of the angles are equal.
The angles that are equal measures 62° each.
Therefore triangle OQR is an isosceles triangle. This means that

Hence,

units.
Answer:
Not completely sure if this is correct but I got
a: 12
b: 24sqrt2
h: 8sqrt2
Step-by-step explanation:
It is a quadratic
where x-8 is the squared term
do
x-8=u
u^2-13u+30=0
solve
u=

u=

u=

u=

u=

u=

or u=

u=10 or 3
10=x-8 or 3=x-8
18=x or 11=x
x=11 and/or 18
