Answer:


First we calculate the slope (which is called "m".


Slope = m = (Y2 -Y1) ÷ (X2 -X1)


m = (-8 -1) / (5 -2) = -9 / 3 = -3


We next fill in this equation: b = y -mx


We know m = -3 and we can choose a point (2, 1) to calculate "b"


b = 1 --3 * 2 b = 7


Putting this into y = mx +b


y = -3x +7

Find the missing angles. will give brainliest if done correctly.
NISA [10]

Answer:

<h2><u><em>x = 69°</em></u></h2><h2><u><em>V = 103°</em></u></h2>

Step-by-step explanation:

the sum of the interior angles in a triangles is 180°, take away from 180 the know angles (34° and 77°) and you will have your answer

180 - 34 - 77 = 69°

Now we find angle V

The angle V and the angle of 77 ° are on a straight line, so the sum is 180°, from 180° you subtract 77 ° and you have the value of V

180 - 77 = 103 °
