Question

Help me with geometry please

Answer 1

y=95

Explanation:

we know that the triangle angles sum is 180°

to find Y you should find x

we are going to find x, we know that a straight angle is 180, to find the x you should:

`120+x=180`

move 120 to the other side with a negative sign:

`x=180-120\\x=60`

angle
`x=60`

now we know enough angles to find y:

`25+60+y=180`

25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:

`25+60+y=180\\85+y=180\\y=180-85\\y=95`

Answer 2

y= 95.

180°-120°=60° (adding 120° with x should give you 180°)

x=60°

25°+60°=85°

180°-85°=95
