- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 35°
Opposite Leg BC = <em>x</em>
Adjacent Leg AC = 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Tangent]: tan35° = x/2
- Isolate <em>x</em>: 2tan35° = x
- Rewrite: x = 2tan35°
- Evaluate: x = 1.40042
- Round: x ≈ 1.40
Hey mate hope its help you...
The beam of light hit the dolphin at the common point that is the solution of a system:
.
From the second equation express y: y=10-x and substitute it into the first equation:
.
Therefore, the horizontal distance in feet is x=5 ft and the height above water is y=10-5=5 ft.
Answer: the beam of light hit the dolphin at 5 ft above water
Answer:
26 ft.
Step-by-step explanation:
1) First I would suggest swapping 8 and 2/3 from a mixed number into a fraction:
8 2/3=8+2/3=(24/3)+(2/3)=26/3
2) Next you just need to multiply the number of shelves John wants to make by the required amount of lumber. He wants to make 3 shelves and each one requires 8 2/3 ft. of lumber, which(as we found above) is 26/3 ft. of lumber:
3×(26/3)=26
So John will need 26 ft. of lumber for his shelving.
Answer: 256 units squared
Step-by-step explanation:
So basically you times 4*4*2*8.
