In the diagram, transversal tcuts parallel lines a and b. Which equation is necessarily true? OA
mZ1 = M27
OB
m23=m26
OC m25+ m28 = 90°
OD
m26+27= 180°

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

i believe the answer is y=0.25x+-3

i don't even know how to read that, ill try to do it if you translate it into english.

answer is a. 13.268 l know it is
