Answer:

B

Step-by-step explanation:

we know that sum of all angles = 180°

A + B + C = 180°

(2x+7) + (4x-10) + ( 7x-25) = 180°

2x + 7 + 4x - 10 + 7x -25 = 180°

2x + 4x + 7x +7 -10 - 25 = 180°

13x - 28 = 180

13x = 180+ 28

13x = 208

x = 208/13

x = 16

∠B = (4x - 10) = 4(16) - 10

= 64 - 10 = 54

∠B = 54°

Hey there!

\left[\begin{array}{ccc}\boxed{\boxed{ \frac{6}{4}}} \end{array}\right] =  \left[\begin{array}{ccc}\boxed{\boxed{150}}\end{array}\right]

All I did was to multiply each side by 100 which then go me this!

Hope this helps!

EXPLAIN THE ERROR Cody was given two points (1/2,4) and (2/3,1), on a line and asked to create a linear equation in standard for
inessss [21]

Answer:

Cody made a mistake when calculating the slope of the line and this affected every other steps after than.

She divided -3 by 6 instead of -3 by 1/6

Step-by-step explanation:

Given

(x_1,y_1) = (\frac{1}{2},4)

(x_2,y_2) = (\frac{2}{3},1)

<em>See attached for steps</em>

Required

Explain Cody's error

<em>Cody made a mistake when calculating the slope of the line and this affected every other steps after than.</em>

See Proof

Slope (m) is calculated as thus:

m =\frac{y_2 - y_1}{x_2 - x_1}

m =\frac{1 - 4}{\frac{2}{3} - \frac{1}{2}}

m =-\frac{ 3}{\frac{1}{6}}

m = -3/\frac{1}{6}

m = -3 * 6

m = -18

This is in contrast to m = -\frac{1}{2}, calculated by Cody

Solving further to determine the equation.

y - y_1 = m(x - x_1)

Where

(x_1,y_1) = (\frac{1}{2},4)

m = -18

y - 4 = -18(x - \frac{1}{2})

y - 4 = -18x + 9

Collect Like Terms

y + 18x = 9 + 4

y + 18x = 13

Write an expression describing all the angles that are coterminal with 141°.
MA_775_DIABLO [31]
<span>The coterminal angles of angle A are given by adding k times 360° to it, where k is an integer, positive or negative. Similarly, all angles that are coterminal with 141° are given by 141° + k * 360° where k is a positive or negative integer. That is 141° + 360°, 141 + 2*360° , 141+3*360° and so on and 141° - 360°, 141° -2*360°, 141° - 3*360° and so on. 9720)</span>
