A circle is 360°.
Add the known angle measures and subtract the total from 360°.
115+105+60 =280°
360 - 280 = 80°
X= 80°
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)
m =
= - 
A=p(1+i/m)^mn
A=980×(1+0.08÷4)^(4×5)
A=1,456.23
BC would equal the same as EF, they are similar. All you would have to do is figure out the pre image (BC) of EF.
