Question

Help pls dont give just the answer pls step by step so i can understand

Answer 1

y=14

Explanation:

Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.

`50 = 2x \\x=25`

plug in 25 in 2x and you would get 50°

Since the sum of a triangle is 180° you could set up an equation
`50+50+5y+10=180`

Then, add 50+50=100+10=110

then you would then have
`5y+110=180\\`

subtract 110 from 180, leaving you with 70

`5y=70`

then divide and you would get 14

Check:

5(14)+10+50+50= 180
