Remember that
If two triangles are congruent, then its corresponding angles and corresponding sides are congruent
In this problem
triangle MTW and triangle BGK are congruent
that means
mmmso
Find the value of x
we have that
msubstitute given values
4x-3=45
4x=48
x=16
Find the value of y
we have
step 1
Find the measure of angle M
msubstitute
mmmstep 2
Find the value of y
we have
m94=11y+6
11y=94-6
11y=88
y=8
