Answer:
x=√-y^2-10y
Step-by-step explanation:
step 1:add y^-2 to both sides
x^2+(y+5)^2=25
x^2+y^2+10y+25+-y^2=25+-y^2
x^2+10y+25=-y^2+25
Step 2:add -10y to both sides
x^2+10y+25-10y=-y^2+25+-10y
x^2+25=-y^2-10y+25
step 3:add -25 to both sides
x^2+25-25=y^2-10y+25-25
x^2=-y^2-10y
step 4:take square root
x=√−y^2−10y
Step-by-step explanation:
3(1+5) (distributive property)
= 1(3) + 5(3)
= 3 + 15
= 18 (answer)
Answer:
Angle C = 45 degrees
Step-by-step explanation:
All interior angles of a triangle add up to 180 degrees.
180-72-63 = angle C
Angle C = 45 degrees
