Step-by-step explanation:

Equation for circle centered at origin:

x² + y² = r².

Therefore r² = (-4)² + (-2)² = 20, r = √20.

Hence d = 2r = 2√20 = 8.94 (2d.p.)

Can someone please help me with the answer

pychu [463]

Answer:

$x = \frac{46}{3}$

Step-by-step explanation:

A straight angle is equal to 180° degrees. Since both 9x +4 and 3x -18 is supplementary then I can make this claim below

$(9x + 4 ) + (3x - 8) = 180$

All we have to do now is to solve for x

$(9x + 4) + (3x - 8) = 180 \\ 9x + 4+ 3x - 8 = 180 \\ 12x - 4 = 180 \\ 12x = 184 \\ x = \frac{184}{12} \\ x = \frac{46}{3}$
