Answer:
The first incorrect justification is in step 2.
Step-by-step explanation:
<u>Step 2</u>. BC2 = AC • DC
2. BC ÷ DC = BC ÷ AC because triangle ABC is similar to triangle BDC
It's supposed to be AC ÷ BC not BC ÷ AC.
Answer:
Area of a circle=pi*(radius)^2
Diameter=2*radius
=> radius=5 m
Area=3.14*(5)^2=3.14*25=78.5 m^2
Step-by-step explanation:
-9x - 2
-9 (7) - 2
-63 - 2
-65
Y - y1 = m(x - x1)
slope(m) = 13
(-2,5)...x1 = -2 and y1 = 5
sub...pay attention to ur signs
y - 5 = 13(x - (-2)...not done yet
y - 5 = 13(x + 2) <== point slope form
