What is the area of this figure?

70

Step-by-step explanation:

We know that to find the area of a triangle, you need is formula:

(base*height)/2

The height is 10 m and the base is 14 m, so the area is:

(10 m*14 m)/2

=140 m/2

=70 m

The area of the triangle is 70 m.

the least common denominator is 40

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
