If BE bisects _ABD and mŁABE = 28°, find m_ABD.

slamgirl [31]

Answer:

m<ABD = 56 degrees

Step-by-step explanation:

If a segment/ray/line bisects an angle, it divides it into 2 equal parts

Since BE bisects ABD, it will divide it into 2 equal parts, one of which is 28 degrees (given)

Now we can find the measure of ABD by doing 28*2=56

Determine the complement and/or supplement of each angle. If it is not possible, explain.

Alecsey [184]

Answer:

complement: 32.8°
supplement: 122.8°

Step-by-step explanation:

The sum of an angle A and its complement C is 90°:

A + C = 90°

C = 90° -A . . . . . subtract A from both sides.

That is, the complement of an angle is found by subtracting the angle from 90°.

The sum of an angle and its supplement is 180°. This means the supplement of an angle is found by subtracting the angle from 180°. You may notice the supplement is 90° more than the complement.

A + S = 180°

S = 180° -A = 90° +(90° -A)

For the given angle, the complement is ...

C = 90° -57.2° = 32.8°

And the supplement is ...

S = 180° -57.2° = 122.8°

<em>Additional comment</em>

We generally like angle measures to be positive (as with all measures in geometry). Hence, we might say that the complement of an angle greater than 90° does not exist. YMMV

What I the equation in standard form of the line that passes through the points(4,-8) and has a slope of 1/4

valentinak56 [21]

Answer:

Standard form of the line with point (4,-8) and slope of 1/4 is

-x + 4 y = -36.

Step-by-step explanation:

The slope of the line equation = 1/4

The point is given as (4,-8).

Now, by POINT SLOPE formula,

The line equation with slope m nad point (x0,y0) is given as:

(y - y0) = m (x -x0)

So, the line equation here is given as

$y -(-8) = \frac{1}{4} (x -4)\\\implies 4(y + 8) = x - 4\\4 y + 32 = x - 4\\4y = x - 36$

Now, the standard form of line equation is Ax + By = C

Here, 4y = x - 36 ⇒ 4y - x = -36

or, -x + 4y = -36 is the standard form.

Hence,standard form of the line with point (4,-8) and slope of 1/4

is -x + 4y = -36.
