Answer:
Step-by-step explanation:
Let point 
be the point where the straight line drawn from point 
meets the straight line 
, it is evident that 
and 
is similar given that both triangles share the same angle, 
. Hence, the ratio of the sides of each triangle is the same. Specifically,
.
Performing cross multiplication yields
.
The anwser is C!!!!!!!!!!!!!!!!!!!!!! ik this because i calculated it my self
Answer:
a= 2/b-c
Step-by-step explanation:
We want isolate for a or to be itself
ab-ac=2
factor out a
a (b-c)=2
Now bring b-c to the other side
a (b-c)/(b-c)=2/b-c
The b-c cancel each other out
a= 2/(b-c)
I’m assuming you man degrees? Are these angles of a triangle?
This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180
Combine like terms to get
2x+202=180
Then subtract 202 from both sides
2x=-22
So x would be -11 which doesn’t seem right lol
