(3.5,1.5) that's the answer hope it works!!!
Answer:
c, i and 3
Step-by-step explanation:
if you look at the congruence signs, then you will see that the 70 degree angle is in the same place.
Let x=height. then base is x+4. plug what we know into the formula for the area of a triangle
A=½bh
16=½*(x+4)*(x)
32=x²+4x
x²+4x-32=0
(x+8)(x-4)=0
so x can be-8 our 4. when we plug-8 in for x we get a negative height. since a triangle cannot have a negative side length we discard-8 and try 4. height=4 and base=8
The answer is -49 because you multiply by 7.
