Answer:
angle 1 = angle 2 = 17 degrees
A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.
Hope this helps :)
Answer:
Step-by-step explanation:
You used Pythagorean theroem which is correct as this does form a right triangle however 50 is the hypotenuse as the ladder is propped up against the wall. 30 would then be the height of the triangle and the base is unknown so...
50 squared minus thirty squared gives 1600 so:
Therefore x is the square root of 1600 which is 40
17-9=8
3x2=6
8x6=48
48/2=24
24
The answer is A
as the x+ 4 is when we replace x with 0
x=0
so
y=0+4
=4
So the line of y must intersect at (0,4) coordinate
which is given as in A and should be a positive slope
