We know that a triangle equals 180 degrees in total. We also know one of the angles so we can do 180-84= 96. This means that the other two angles must be equal to 96 degrees. We then set up (x+59)+(x+51)=96 "since both of the angles must add up to 96." Then we add like terms and get 2x+110=96. Further simplification gives us x= -7. Plug this into both angles and you get that angle A is 44 degrees.
Answer:
Supplementary Angles.
Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don't have to be together.
Answer: x-y=2
Step-by-step explanation:
y+5=x+3; move variable (x) to the left-hand side and change the sign.
y-x+5=3; move the constant to the right-hand side & change the sign
y+x=3-5; reorder the terms
-x+y=3-5; calculate
-x+y=-2; change the signs on both sides
x-y=2 is your answer! hope this helps!
