Answer:
A
Step-by-step explanation:
Area of a triangle = 
where b = base length and h = height
the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5
So area =
5.5 also = 
Hence, the correct answer is A
Answer:
y=1.4x+6.8
Step-by-step explanation:
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
y=1.4x+6.8
[c] 70°
40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles
Answer:
A.
Step-by-step explanation:
for a single element of x there is an element in y, so observing we see that no number is repeated in the ordinate x of the coordinates
