Answer:
h ≈ 66.4 ft
Step-by-step explanation:
The situation can be modelled by a right triangle with h representing the height of the tree.
Using the tangent ratio in the right triangle
tan39° = 
= 
( multiply both sides by 82 )
82 × tan39° = h , then
h ≈ 66.4 ft ( to the nearest tenth )
Answer: D
Step-by-step explanation:
Remember that the Opposite side to an angle is in the same order of length as the Angle. So, 
. Using Cross multiplication, this answer can be solved:
, 60 x 12 = 720, and 90 x 8 = 720. N = 8.
, 30 x 12 = 360, and 90 x 4 = 360. N = 4
Answer:
-16
Step-by-step explanation:
So let’s solve for 7x. So 7x=34. So 7x-50 is 34-50 or -16
Answer:
72
Step-by-step explanation:
use a percentage calculator! Hope this helped! <3
3.) The answer is 120 times. Because for one month, the stoplight was red for 10 times. So 12 × 10 = 120 times
4.) Answer: 72. Because 12 × 6 = 72.
5.) Answer: 48. Because 12 × 4 = 48.
Hope it helps. ^_^
