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)
I hope it’s correct
The answer:
5-4v=19
It will reach 80 feet for the second time after 5 seconds.
We set the equation equal to 80 feet:
80= -16t² + 96t
When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80
We use the quadratic formula to solve:
You divide 91/14 to get w=6.5.
Answer:
C(3, 0)
Explanation:
A(4, 0) and B(3, 7)
<u>When Drawn These Two coordinates</u>
Identify the coordinates which make the triangle 90° (right angle triangle)
<u>Stated that the Point C is on the x-axis</u>, the value of y will be 0
Coordinates of C: (3, 0)
