Answer:
<h3>11.8 feet</h3>
Step-by-step explanation:
Given
Length of the ladder = 12foot
angle of elevation = 80 degrees
Required
Height of the wall (opposite side)
The set up will form a right angled triangle where
length of the ladder is the hypotenuse
height of the wall is opposite;
Using SOH, CAH, TOA trig identity
According to SOH
sin 80 = opp/hyp
sin80 = opp/12
opp = 12sin80
opp = 11.82 feet
Hence the height of the wall is 11.8feet (to the nearest tenth)
<span>C and B are *candidates* for being the correct solution
because f(2) = 4 for both.
</span>
A is the correct solution because f(3)=6
Answer:
= -10d^4 + 12d^2s + 25d^2 - 30s
Since 30 times 5= 150, he worked 150 hours for the rest of the week.
