Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
Answers:
- Angle A = 76
- Angle B = 37
- Angle C = 67
Triangle ABC is an acute triangle. It's also a scalene triangle.
====================================================
Work Shown:
x = measure of angle B
2x+2 = measure of angle A, since we're told its "2 more than twice angle B"
2x-7 = measure of angle C, for similar reasoning
The three angles add to 180. This is true for any triangle
A+B+C = 180
(2x+2)+(x)+(2x-7) = 180
5x-5 = 180
5x = 180+5
5x = 185
x = 185/5
x = 37
This means angle B is 37 degrees. The other two angles are
A = 2x+2 = 2*37+2 = 74+2 = 76
C = 2x-7 = 2*37-7 = 74-7 = 67
----------------
In summary, we have these three interior angles
As a way to check, note how A+B+C = 76+37+67 = 180. This confirms the answer. All three angles mentioned are smaller than 90 degrees, so this triangle is acute.
Furthermore, because all three angles are different measures, this means all three sides are different lengths. This leads to triangle ABC being scalene.
