Answer:
90deg
Step-by-step explanation:
If the angles are supplementary, that means mA + mB = 180*
we know that
mA = (2x + 8)deg
mB = (2x + 8)deg = mA
mA + mB = 180deg
mB + mB = 2mB = 180deg
mB = 90deg
Note, that we did not need to compute x even, because the angles were the same.
Answer:
x=12
Step-by-step explanation:
If the triangles are similar:
x/8=18/12
x/8=1.5
x=12
X² + y = 4 and -y³ = 1x -5 are not linear equation because they contain a variable with a exponents. These types of equation are called quadratic equations.
Answer:
b and d
Step-by-step explanation:
Under a reflection in the x - axis
a point (x, y ) → (x, - y ) , then
H (9, 1 ) → H' (9, - 1 )
the x- coordinate is 9 → b
the y- coordinate is - 1 → d
