Answer:
60 is your answer.
Step-by-step explanation:
x - 8 = 10
add 8 to both sides,
x = 18
substitute 18 for x in the second equation:
4(18) - 12 = 72 - 12 = 60
Please lmk if you have questions.
Answer:
-multiply both sides by 2, so you will have 2A= h(b+c)
- divide both sides by (b+c), so you will have 2A/(b+c)=h and this is your final answer
ΔABO is a right triangle with AB⊥BO. The radius of the circle is BO. The Pythagorean theorem applies.
AO² = AB² + BO²
13² = 5² + r²
169 -25 = r²
r = √144 = 12
The radius (r) is 12.
