The ladder is making a right triangle so just use sin, cos, and tan to find either of the unknown angles.
(a) Using sin, you can find the missing angle and come up with the equation sin<span>ø = 9.2/10
</span><span>ø=80 degrees
</span>(b) Using a different triangle where the height of the building is unknown but all the angles are known. You can use cos to find the length of the base of the triangle.
cos75=x/10
x=9.2 ft

This is crazy. If I'm reading this right (I'm not sure why there are spaces put in between some of those numbers like there is), I'm getting that the answer is
-1079.242293. But again, those spaces are throwing me off. I eliminated the spaces between the numbers while I was performing the operations in order.

0.73 recurring can be writeen as 11/15

Minchanka [31]

Answer:

yes , see explanation

Step-by-step explanation:

We require 2 equations with the recurring 3 placed after the decimal point.

let x = 0.7333.. ( multiply both sides by 10 and 100 )

10x = 7.333... → (1)

100x = 73.333.... → (2)

Subtract (1) from (2) , eliminating the recurring 3
