Step-by-step explanation:
sum of the ratio=3+3+4=10
now,
angle I = 3/10×180=54
angle II= 3/10×180=54
angle III=4/10×180=72
that shows th given triangle is isoceles
15x = 5y divide by 3, 3x=y. I believe
Step 1
<u>Find the value of x</u>
we know that
-------> by corresponding angles, because the given lines are parallel
Solve for x

Step 2
<u>Find the value of y</u>
we know that

substitute the value of x and solve for y





therefore
<u>the answer is the option B</u>
