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.
Since it is two negatives you are actually adding so -3 +4 would equal 1
The hundredths place value was rounded.
Answer:
it's the last one.
Step-by-step explanation:
both of them have ÀF as part of their angle.
