Answer:
101.58 in
Step-by-step explanation:
The ramp r is the hypotenuse of a right triangle with the ground and 28 in height being the legs.
The angle of elevation 16° is the angle inside the triangle opposite the 28 in height.
Using the sine ratio in the right triangle, then
sin16° = = ( multiply both sides by r )
r × sin16° = 28 ( divide both sides by sin16° )
r = ≈ 101.58 in
Triangle ABC is a scalene triangle because all of it's sides are not equal.
Answer:
8/15
Step-by-step explanation:
KCF (Keep, Change, Flip)
keep 2/5, change ÷ to ×, flip 3/4 to 4/3
2/5 × 4/3
2×4=8
5×3=15
8/15
Hope it helps :)
