Enter the value of 7.(2+18) -14

we are going to use BODMAS

7.(2+18) -14

is also 7×(2+18) -14

since B representing bracket comes first,

we add the numbers in the bracket.

2+18=20

7×(20) -14

then M representing multiplication comes next do we multiply.

7×20=140

140-14=126

that's it!

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,
