H, being an unknown number less than 30
30-h
you are taking away h because it is (h) amount less than 30
Answer:
x = 63
Step-by-step explanation:
The sum of the angles of a triangle is 180
71+46+x = 180
Combine like terms
117+x =180
Subtract 117
117+x-117= 180-117
x =63
Equating the y's:-
3x + c = x^2 - 5x + 7
x^2 - 8x +7 - c = 0
If y = 3x + c is a tangent then there will be duplicate solutions to this equation
That is the discriminant b^2 - 4ac = 0. So we have:-
(-8)^2 - 4 * 1 * (7 -c) = 0
64 -28 + 4c = 0
4c = - 36
so c = -9 answer
Answer:
it would be 61 tiles i think
Step-by-step explanation:
Answer:
x= 90 degrees because AD is the perpendicular bisector and the angle bisector
y=86 degrees because 47+47+86=180
