<h3><u>Answer:</u></h3>

<h3><u>Solution</u><u>:</u></h3>
we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:

Here,
- hypotenuse = 23 feet
= 76°- Value of Sin
= 0.97 - Perpendicular = ?

Shifting down 4 means you are taking away 4.
F(x) = g(x) - 4 = 3x^2 - 4
Opposite angles are equal, so we know that C=2x and D=5x+5 as well.
The sum of the interior angles of any quadrilateral is 360, so we have

So, the measures of the angles are

Answer:
1. n + 8 = 10
2.
= 10
3. 8n - 6 = 34
4. 3(n + 12) = 45
5. No
6. Yes
Step-by-step explanation:
(only for questions 5 and 6)
5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.
6. If you substitute in b = 8, you get:

this is true.
