Answer:

Option B, 63 + a = 90; subtract 63 from both sides of the equation

Step-by-step explanation:

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Here, we know the one angle measure is 63°

Let's consider unknown angle as a.

63 °+ a = 90°

63 °+ a -63° = 90° - 63° ( subtract 63 from both sides of the equation)

a = 90° - 63°

a = 27°

Hey there!

The equation of a circle which passes through any point having centre (h,k) is;

$( {x - h)}^{2} + ( {y - k)}^{2} = {r}^{2}$

In first blank ( x-_ ) keep "-2". In second blank (y - _ ) keep "4" and in last blank ( _ ) keep "36".

Hope it helps..

What is the equation of the line that passes through the point (8, -4) and has a slope of 1/2

Eva8 [605]

Answer:

$y = \frac{1}{2}x - 8$

Step-by-step explanation:

1. Approach,

For this problem, the format of a line that will be used is, slope-intercept form;

$y = mx + b$

Where ( $m$ ) is the slope of the line, also known as the change in the line and $(b)$ is the y-intercept, or where the graph of the line intersects the y-axis. Since, in this problem, the slope of the line is given, all one has to do is substitute in a point on the given line and solve.

2. Finding the equation,

In this problem, the slope of the line is given. Therefore, to solve this problem, all one has to do is substitute in a point on the given line and solve.

$y = mx + b$

Substitute in the slope,

$y = \frac{1}{2}x + b$
