<h2>Answer</h2>
Angle A = 54 degree
Angle B = 72 degree
Angle C = 54 degree
<h2>Explain</h2>
It is a triangle, so the total of angle is 180 degree
Find X
8x + 6x + 6x = 180
20x = 180
x = 180/20
x = 9°
Value of x is 9°
Substitute a score of x for every angle =
Angle A
= 6x
= 6(9)
= 54°
Angle B
= 8x
= 8(9)
= 72°
Angle C
= 6x
= 6(9)
= 54°

Step-by-step explanation:
Answer:
It would be 6.75%
Step-by-step explanation:
Because, if you divide 18 by 37.5%, you will get you answer (6.75%)
Multiply bottom equation by -3 to add and eliminate y’s.
So...
5x-15y=10
+-9x+15y=18
You get -4x=28 so x=-7
Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3
Check in other equation
3(-7)-5(-3)=
-21+15=-6
So x= -7 and y= -3
