What is the value of y?

Enter your answer in the box.

y=

5 degrees

Step-by-step explanation:

Triangle all angles=180

180-75=105

Both Sides are equal

105-75=30

30=4y+10

30-10=20

20/4=5

5 is the Answer

HOPE IT HELPS!

y = 5

x = 25

Step-by-step explanation:

B and C are both base angles, so they are equal to each other;

[Equation] 75 = 3x

[Divide both sides by 3] x = 25

Then, all angles of a triangle added up together are equal to 180 degrees;

[Equation] 75 + 3x + 4y + 10 = 180

[Plug in x]  75 + 3(25) + 4y + 10 = 180 -> 75 + 75 + 4y + 10 = 180

[Subtract 160 from both sides] 4y = 20

[Divide both sides by 4] y = 5

Have a nice day!
