Find the value of Y, 14 points

should be 125°

Step-by-step explanationz, y, and x make a 180° line. 52+3=55 and subtracting that from the total 180°gives you 125

y = 8

Step-by-step explanation:

1. subtract 52° from 180° to get the value of the obtuse angle

2. that leaves you with 128° and now you subtract from 180° again bc the angles of a triangle always add up to 180° and so you have 52° now

3. the two angles you dont have add up to 52° and from here you write the equation 3y + 4y - 4 = 52

4. combine like terms to simplify the equation so you have 7y - 4 = 52.

5. add 4 to both sides so you get 7y = 56 nd then divide both sides by 7 leaving you with y = 8

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
