Answer:
∠ R 90°
Step-by-step explanation:
Given that in triangle RST
Now as per condition one angle is greater than sum of other two angles.
Since in triangle ,sum of all three angles = 180°
Hence if one angle is 90° then sum of other two must be equal to 90°
And if one angle is 90° then only other two angle be 45° each
Here Let if angle s = angle T = 30° then with this condition angle r is 120° , which is greater than 90°
So, from above it conclude that
For ,
∵ ∠ R = 120° , then it is greater than 90°
I.e , ∠ R 90°
Answer
Answer:
a) $32,000
b) 9/25
c) 36%
Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
- 18,000/50,000
- 9,000/25,000 => SImplify
- 9/25 => Simplify
It's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?
Convert the fraction to percent
- 9/25
- 9*4/25*4 => Denominator of 100
- 36/100
- 36%

Answer:
Plot these points
(-3,0)
(-5,0)
(-4,1)
(-2,-3)
(-6,-3)
Step-by-step explanation:
Let find the zeros of the equation.
We can factor this equation.
Factor out the -1.
Factor using AC method
Set all the terms equal to zero.
So our x intercepts are -3,0 and -5,0.
To find our vertex, apply the -b/2a.
Then
Substitute-4 for x.
So our vertex is at (-4,1).
Find some other points like -2 and -6.
To find -2, substitute-2 into the quadratic.
So -2,-3.
Since y=-4 is the axis of symmetry
-6,-3
