Answer:
The angles in the triangle and 10, 80 and 90
Step-by-step explanation:
The two angles that are left in a right triangle add to 90 degrees
8:1 means that there total is 9
8x+1x = 9x
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
8*10 = 80
1*10 = 10
The angles are 80 and 10
if the depth is based off of the original spot where the penguin is, then 13 ft.
if not, 10 ft.
x = - 1
Given
2 = 3x + 5 ( subtract 5 from both sides )
- 3 = 3x ( divide both sides by 3 )
- 1 = x
1
9-8=1
Hope that this is helpful.
Have a nice day.
