Answer: y= -1
Step-by-step explanation:
Add 5 to both sides,
y-5+5=-9y-15+5
Simplify,
y=-9y-10
Add 9y to both sides,
y+9y=-9y-10+9y
Simplify,
10y=-10
Divide both sides by ten.
10y over 10 = -10 over 10
There you go!
I think it’s 3. Sorry if I’m wrong tho
The answer for 5. is y+5. In an isosceles triangle, 2 of the sides are congruent. If the base is 4y+2, the other 2 sides must equal to 2y+10. Since both sides are congruent the only answer would be y+5.
Hope that helped :))))
The answer is 80 degree just subtract 90 from 10
