<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 = ?

Answer:
3
Step-by-step explanation:
For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c
Where m represents the slope and c represents the y intercept
Now let’s take the last point on the table;
and substitute the values of x and y;
we have;
10 = 2m + c. ••••••••(i)
let’s take the second to the last;
7 = m + c ••••••••••(ii)
So let’s solve both equations simultaneously
Just subtract second from first directly
This gives m = 3
