Answer: 11.3 feet
Step-by-step explanation:
The question is not structured properly but assuming the ramp should have a slope of 12 feet then this can be solved with the Pythagorean theorem.
a² + b² = c²
a is the height above the ground
b is the distance of the ramp's beginning from the entrance
c is the slope
4² + b² = 12²
16 + b² = 144
b² = 144 - 16
b² = 128
b = √128
b = 11.3 feet
Answer:
55°
Step-by-step explanation:
What we have are vertical angles. Vertical angles are angles directly opposite to one another.
Importantly, the measures of vertical angles are equivalent. Thus, set the expressions to each other and solve for x:
Subtract 3x from both sides:
Subtract 6 from both sides:
Divide everything by 4:
Flip:
Now, substitute this back into either of the equations since we know they are the same:
Multiply:
Add:
So, the angle is 55°

Step-by-step explanation:
56/2 = 28 times.
So 2 goes into 56 28 times.
