Answer: well i think it is B
Step-by-step explanation:
Is there supposed to be a graph or another picture? I do not see anything.
See the attached figure which represents the explanation of the problem.
Let <span>the height of the building = h
</span>
∵ ∠1 congruent to ∠2
∴ ∠1 = ∠2
∴ tan (∠1) = tan (∠2) ⇒⇒⇒ tan of the angle = (opposite/adjacent)
∴

∴ 12 h = 5 * 264 = 1,320
∴ h = 1,320/12 = 110 feet
∴ T<span>
he height of the building = 110 feet</span>
Answer:
B. 30
Step-by-step explanation:
The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.
85 = 3x - 5
We need to solve for x.
First, combine like terms by adding 5 to both sides.
90 = 3x
Now we want to isolate x by dividing both sides by 3.
x = 30
This is your answer.
Let's check our work by plugging x back into our equation.
85 = 3x - 5
85 = 3(30) - 5
85 = 90 - 5
85 = 85
Your answer is correct.
Hope this helps!

Andrea: K
Me: 5k - 4
Sum
k + 5k - 4 = 14
Solve
6k - 4 = 14 Add 4 to both side.
6k - 4 + 4 = 14 + 4
6K = 18 Divide by 6
k = 18/6
k = 3
