Answer:

Step-by-step explanation:

Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
To find the answer make 25 equal to 6x+1
25=6x+1
25-1=24
24=6x
24/6=4
x=4
X=4
The answer is 24 because 8 times 3 is 24
The slope is -4 and the y-intercept is -12.
