Im pretty sure it’s 12 miles, hope this helped :)
Here are the basic rules for a right triangle:
One angle is always 90° or right angle.
The side opposite angle 90° is the hypotenuse.
The hypotenuse is always the longest side.
The sum of the other two interior angles is equal to 90°.
The other two sides adjacent to the right angle are called base and perpendicular.
a quick way to find angle 1, is just to look at the figure. there seems to be bisecting angles, so angle FCE and angle 1 are congruent. (meaning angle 1 is also 34 degrees)
hope this helps! lmk.
Answer:
The cubic volume of concrete needed to complete the ramp is 360 ft³
Step-by-step explanation:
We note that the ramp shape is that of a right ngled triangular cube with dimensions
Height = 10 ft
Base = 12 ft
Width = 6 ft
The amount of concrete to fill the ramp is approximately the volume of the ramp.
Volume of ramp = volume of triangular prism = 0.5×Base ×Height × Width
Volume of ramp = 0.5×12×10×6 = 360 ft³.
The cubic volume of concrete needed to complete the ramp = 360 ft³.
