The cube root is 16. Often times, teachers just let you use calculators on these questions.
2/9 is the answer for your question
Answer:
x=33
Step-by-step explanation:
x+(3x+48)=180
combine like terms
4x+48=180
subtract 48 from 180
4x=132
then you divide both sides by 4
x=33.
check your work (plug it in)
33+((33x3)+48)=180
33x3=99
99+48=147
then you add 33 from the other x
147+33=180
The angle of interest is the one at the end of the shadow looking up toward the flagpole. Thus the length adjacent to the angle is that of the shadow, 22 ft. The length opposite the angle is the height of the flagpole, 45 ft. The tangent of the angle is the ratio of the opposite length to the adjacent one.
... tan(angle) = (45 ft)/(22 ft)
... angle = arctan(45/22) ≈ 63.9° . . . . . matches selection A.
