Sagot :
Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64
Answer:
Hey it's me again the life saver ;)
To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a
a=>
53 + 47 + a = 180
a=180 - 100
a=80°
Now to find b=>
80 + 69 + b =180 (Because of Linear pair property)
b = 180-149
b=31°
Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°
c=>
31 + 85 + c =180
c=180 - 116
c=64
Hope it helps
