Solve each question for X , y=-9+x^2
2 answers:
So basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
x=
Y = -9 + x^2
y + 9 = -9 + 9 + x^2
y + 9 = x^2
√y+9 = <span>√x^2
</span><span>√y+9 = x
</span>x = <span>√y+9
</span><span>√ is the square root symbol</span>

Answer:
Again every triangle is 180° and so is every straight line, so 180-105 is 75° so 75°+85° is 160 and 180-160 is 20° so your missing angle is 20°
