Answer: Option D
Step-by-step explanation:
Hey there!
Here; Looking at it we can state that it is a Right angled triangle.
<u>And</u><u> </u><u>must</u><u> </u><u>use</u><u> </u><u>the</u><u> </u><u>Pyth</u><u>agoras</u><u> </u><u>relat</u><u>ion</u><u> </u><u>if</u><u> </u><u>the</u><u> </u><u>trian</u><u>gle</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>Right</u><u> angled</u><u> triangle</u><u>.</u>
<u>So</u><u>,</u><u> </u><u>let</u><u>'s</u><u> </u><u>wo</u><u>rk</u><u> on</u><u> </u><u>it</u><u>.</u>
Let ABC be a triangle.
Taking reference angle as C, we get;
perpendicular= 3m
Hypotenuse= 7m
Base = xm
Now;

Lets convert the fractions first:
85 1/3 = 255/3 + 1/3 = 256/3
10 2/3 = 30/3 + 2/3 = 32/3
now, the equation to find the area of a triangle is:
area = height*base/2
so the height is:
height = 2*area/base
then we substitute:
height = 2*(256/3)/(32/3)
= <span>(2*256/3)/(32/3)
</span><span>= (512/3)/(32/3)
</span>now, dividing by a fraction is the same as multiplying by that fraction upside down:
= <span>(512/3)(3/32)
</span>= (512*3)/(3*32)
= 1536/96
= 16
therefore the height of the triangle is 16 ft
