Question

I am starting to get this but, each question is a different subject so plz help asap. Btw these are not test or quiz questions. They are just practice questions so I know how to do it before a test or quiz.

Answer 1

73 degrees

Explanation:

Given

A Shaped Frame of two congruent sides

Required

Determine the angle made with the ground

Given that there are two congruent sides, this implies that the A frame is an isosceles triangle;

Let the two angles made with the ground be represented by x

Angles in a triangle when added equals 180;

Hence;

`x + x + 34 = 180`

`2x + 34 = 180`

Subtract 34 from both sides

`2x + 34 - 34 = 180 - 34`

`2x = 180 - 34`

`2x = 146`

Divide both sides by 2

`(2x)/(2) = (146)/(2)`

`x = (146)/(2)`

`x = 73`

Hence, the angle with the ground is 73 degrees
