Answer:

84 feet to the nearest foot.

Step-by-step explanation:

We have a right angled triangle with adjacent side (A) = 100 and you want to find the height of the tower, the opposite side (O).

A = 100 , O = ? so we need the tangent , (from SOH-CAH-TOA).

tan 40 = O/ 100

O = 100 tan 40

= 83.9 feet.

Answer:

The ceiling is lower than 3 meters.

Step-by-step explanation:

In the above, the product is <em>less than</em> 3. In this case, it will not include 3 as a choice, as if it would, the \leq would be used.

This means that x would be any number that is less than 3. The only choice that gives a choice that means less than by the terms definition is A) The ceiling is lower than 3 meters.

11) The measure of each interior angle of a regular 11-sided polygon is
Svet_ta [14]

Answer:

Step-by-step explanation:

Always , sum of exterior angle of any polygon  = 360

sum of exterior angle of 11- sided polygon  = 360

Measurement of  an exterior angle of 11-sided polygon  = 360/11

                                                 = 32.73

Measurement of  an interior angle of 11-sided polygon = 180 - 32 8/11

= 180 - 32.73= 147.27
