Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2

So the time taken to complete the dive is: 535 minutes
Sorry I don't know if I did well I'm in 3rd grade but that's bn because my sister loat 10I hope you find it useful. have a good day ❤️
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>
