The given information is not sufficient to prove ΔGHI and ΔRST are congruent through SSS congruence.
<h3>What is SSS congruence of triangles?</h3>
As per the SSS congruence of a triangle, if all the three sides of a triangle are equal to the all the three corresponding sides of another triangle, then the two triangles are congruent triangle.
Since one side and two angles of the triangle are given, the triangles can not be proved to be congruent as per the SSS congruence of triangles. Hence, the given information is not sufficient to prove ΔGHI and ΔRST are congruent through SSS congruence.

Make them have common denominators: -2/8 - 3/8 - 6/8 - 7/8 =
Now just do subtraction with numerators: -5/8 - 6/8 -7/8 = -11/8 - 7/8 = -18/8 =
Simplify: -9/4 =
Make it a mixed fraction: -2 1/4 (D)
Answer:
Step-by-step explanation:
Note that the base angle of an isosceles triangle is equal hence;
3x+2 = 5x-30
3x - 5x = -30-2
-2x = -32
x = -32/-2
x = 16
Hence one of the base angle = 3(16)+2 = 50degrees
The sum of angle in the triangle is 180, hence
50+50+y = 180
100 + y = 180
y = 80 degrees
Hence the third angle is 80 degrees
“Y” is equal to 9 because you substitute the x which is 2 and then solve from there
