Y is 163 degrees because it is a vertical angle with the other 163 degree angle and vertical angles are equal.
Answer:
Step-by-step explanation:
Compare the ratios of the triangles like so:
Bigger to smaller

This statement is true. Both fractions simplified are equal to 1.5. Since they have the same ratios, they should be similar.
-2y-4=4(y-1)
Always remove the pararentheses as your first step.
-2y-4 = 4y - 4
Combine like terms.
-2y - 4y = 4 - 4
-6y = 0
Divide both sides by -6 to find y.
-6y/-6 = 0/-6
y = 0
