Answer:
angle 1 → 45°
angle 2 → 90°
Step-by-step explanation:
Since AC bisects ∠DAB then the measure of angle 1 is 90/2 = 45°
Since Lines AC and BD are perpendicular then the measure of angle 2 is 90°
The number of blue balls that are needed to balance four green, two yellow and two white balls is 16 blue balls.
<h3>Numbers of blue balls needed</h3>
Green(g)
Blue (b)
Yellow (y)
White (w)
First step is to formula an equation
3g=6b
g=2b
2y=5b
y=5/2b
4w=6b
w=3/2b
Second step is to substitute
4g+2y+2w
=4(2b)+2(5/2b)+2(3/2b)
=8b+5b+3b
=16b
Therefore 16 blue balls are needed.

Answer:
the Pythagorean formula is a²+b²=c², which is a and b are the x and y distances between points and c is the hypotenuse, which is the distance.
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
If we have an equation of the form y = mx +b then the y-intercept is b.
So now here we have y =-x - 2. Therefore b = -2 and we conclude the y-intercept is -2.
