Answer:
20.833 feet
Step-by-step explanation:
The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.
Therefore, we can write and solve a proportion.
h / 10 = 6.25 / 3
h = 20.833
The beam is 20.833 feet tall.
Step-by-step explanation:
area of missed triangle =1/2×2×4=4 cm2
area of whole rectangle =4×8=32 cm2
area of shape =32_4 =28cm2
The answer is definitely B
The hypotenuse is always the longest side and it is the side that is opposite the right angle.
