I believe the answer is C, 68.

Angles A and R are supplementary so:
180=x+124
Angle A=56

AFD is an isosceles triangle so angles A and D are both 56. Then you can use these to solve for angle AFD.
180 = x+56+56
x=68

Kristen is 64 inches tall, and she stands 12 feet away from a streetlight. If she casts an 82-inch-long shadow, how tall is the

o-na [289]

Answer:

176.39 inches or

14.70 feet

Step-by-step explanation:

Consider the right triangle made by Kristen, ground and shadow.

This triangle has one leg as 64 inches.

Next consider the right triangle formed by street light, ground upto shadow tip.

The two triangles have common angle of elevation and also another angle as 90 degrees.

Hence the two triangles would be similar

Also if A is the angle made by hypotenuse of both triangles with the ground we have

$tanx=\frac{64}{82}$

This value also equals by bigger triangle as

$tanx=\frac{h}{82+12(12)}=\frac{h}{226}$

From these two we get

h = height of street light = $\frac{226(64)}{82} =176.39$

Leto [7]

Answer:

(Parentheses) P.E.M.D.A.S
Exponents(^)
Multiply(X)
Division(/)
Addition(+)
Subtraction(-)

Step-by-step explanation:

First simplify (20/4-2+1)=

9+5x2(4)=

then simplify again

14x8=112

simplify one more time and you get your answer.

122 is your answer.

So to answer the real question start with parentheses first then work and simplify the equation.
