I've done with my quiz, now I have to do the correction for extra point, bit my teacher required to explain how to solve it corr

lapo4ka [179]

To solve this problem, we have to use the interior angles theorem which states that the sum of all three interior angles of a triangle must sum 180°.

Having said that, we express the following.

$75+x+2x=180$

Now, we solve for x.

$\begin{gathered} 75+3x=180 \\ 3x=180-75 \\ 3x=105 \\ x=\frac{105}{3} \\ x=35 \end{gathered}$

Then, we use this value to find the angle T.

$m\angle T=2x=2(35)=70$ <h2>Therefore, the angle T is equal to 70°.</h2>

Determine the equation of the line passing through the points (-1, 1) and (1, 7).

evablogger [386]

Answer:

$3x + y = -4$

Step-by-step explanation:

We were given to points on the line we are trying to find, hence we are able to determine the slope/gradient.

$( - 1, \: 1) \: and \: (1, \: 7) \\ slope = \frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} } \\ \\ s = \frac{7 - 1}{1 - ( - 1)} \\ s = \frac{6}{2}$

Slope is equal to 3.

Since we have the value for the slope, we can now use one of the points on the line to determine the equation of the line.

note that the coefficient of x is the slope. In this case the A from the standard form (Ax + By= C) is the slope.

$\\ let \: us \: use \: the \: point \: ( - 1, \: 1) \\ a = 3 \: \: \: \: y = 1 \: \: \: x = - 1\\ ax + by = c \\ 3( - 1) + 1 = c \\ - 3 + 1 = c$

$- 2 = c \\ therefore \: the \: equation \: of \: the \\ \: line \: is \\ ax + by = c \\ 3x + y = - 4$
