Answer:
Angle A: 72°
Angle B: 108°
Step-by-step explanation:
Opposite angles are equal
Adjacent angles add up to 180
5y - 3 = 3y + 27
2y = 30
y = 15
Angle A:
5(15) - 3 = 72°
Angle B:
180 - 72 = 108°
Answer:
if the x's are the same 8x is 16
Step-by-step explanation:
if they are supposed to have the same answer, of 24, the answer is 3
THE x IS 2
Answer:
The definition of a bisector is something that cuts an object into two equal parts. This "something" is usually a line or a segment.
Step-by-step explanation:
An angle bisector of a triangle divides the opposite side into two segments that are proportional to the other two sides of the triangle. to create similar triangles. ... An angle bisector is a ray in the interior of an angle forming two congruent angles.
Ok so we'll go ahead and solve for y first - we just need to get it alone on one side of the equal sign
Step 1: subtract 2x from each side
2x - 7y - 2x = 19 - 2x
This cancels out the 2x on the left, giving us
-7y = 19 - 2x
Step 2: divide both sides by -7
=
+ 
This gives us
y = -19/7 + 2x/7
That should be your answer for the first question. Now solving the next parts are easy. All you need to do is plug in x.
When x = -3
y = -19/7 + 2x/7
y = -19/7 + 2(-3)/7
y = -19/7 - 6/7
y = -25/7
When x = 0
y = -19/7 + 2x/7
y = -19/7 + 2(0)/7
y = -19/7
When x = 3
y = -19/7 + 2x/7
y = -19/7 + 2(3)/7
y = -19/7 + 6/7
y = -13/7
Hope that helps! Feel free to ask if I can help with anything else :)
