Answer:

$17 \: \: degrees$

Step-by-step explanation:

$7x + 2x + 27 = 180 \\ 9x = 180 - 27 \\ 9x = 153 \\ \frac{9x}{9} = \frac{153}{9} \\ x = 17 \: \: degrees$

The answer is: b) 17

Check is :
(7x) = (2x + 27)
(7 • 17) = ((2 • 17) + 27)
(7 • 17) = (34 + 27)
119 = 61

119 + 61 = 180 ✅

The points in the table lie on a line. Find the slope of the line.

maria [59]

The slope of the line is $-\frac{3}{4}$

First, you must find 2 points.

(-6,8) (-2,5)

Then, you must substitute the value of the points in.

$\frac{5-8 }{-2+6}$

Finally, simplify the fraction.

$-\frac{3}{4}$

Answer:

4.9 cm

Step-by-step explanation:

To solve this problem you would use the power of a point formula where two chords intersect in the interior of a circle. We get the equation:

7 * 7 = 10 *x

49 = 10x

x = 4.9 cm
