I need help with this

x = 85

Step-by-step explanation:

To solve, first find the angle of the other missing angle in the left by subtracting the outside angle from 180:

180 - 155 = 35

Then add this and the known angle:

35 + 60 = 95

Then subtract this from 180 to get the missing angle for x:

180 - 95 = 85

answer: (3,11) is your answer.

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
