5x +4y=23
-5(x-4y=-5)

5x+4y=23
+(-5x+20y=25)

24y=48
y=2

Now plug y value into one of the equations and solve for x

X-4(2)=-5
X-8=-5
X=3

So the answer is (3,2)

State if the two triangles are congruent. if they are state how you know.
nlexa [21]
1) The triangles are congruent by SSS.

The two tick marks indicate two pairs of congruent sides; it is evident that the third side is congruent by the way the diagram is drawn - the bases of the triangles are together and appear to be the same length.

2) The triangles are congruent by SAS.

The two pairs of tick marks indicate congruent sides, and their included angles are congruent because they are vertical angles, and vertical angles are always congruent.

marysya [2.9K]
Use your knowledge of trig for this. you know the opposite length, 35, and you need to find the hypotenuse. the trig function to use would be SIN.
\sin(60 ) = 35 \div hyp
