GJ bisects ∠FGH and is a perpendicular bisector of FH.
Aleks04 [339]

Solution:

In \Delta FGH, As, given G J bisects ∠F G H and is a perpendicular bisector of F H.

So, F J=J H →→ G J is a perpendicular bisector of F H.

We will use angle bisector theorem to determine which statement is correct.

As, Angle bisector theorem states that , if a line segment bisects an angle, then the ratio of sides adjacent to angle, is equal to the ratio of two segments where the angle bisector cuts the third side.

So, \frac{GH}{GF}=\frac{HJ}{JF}\\\\ \frac{GH}{GF}=1\\\\ GH=GF

The option (C) which is the  \Delta F G H has exactly 2 congruent sides is true.

2x + 3y =10<br>x + y = 3 please do workings asap
kompoz [17]
This is system of Equations. 
<span>2x + 3y =10
x + y = 3 
</span>
x + y = 3 (multiply this by three) to get 3x + 3y = 9
2x + 3y =10
3x + 3y = 9 Subtract them

-1x = 1 
x=-1 
Now plug x back into the top equation and solve for y. 

I hope this helps! If not, let me know! Have a fantastical day!
