Can anyone help me on that question too its math plsss

Assoli18 [71]

Answer:

2x= 40°

5x= 100°

Step-by-step explanation:

2x on opposite angle because it is an isosceles triangle

2x+ 2x+ 5x = 180° (angles of a triangle)

9x= 180

x= 180/9

x= 20°

Sub

2(20)= 40°

5(20)= 100°

Consider the line y=-3x+3.

emmainna [20.7K]

Answer:

$y= 3x+17; y= -\frac13x +\frac{11}3$

Step-by-step explanation:

First problem. If you want a parallel to a given line, you keep the slope.

Then we use the point-slope form of a line

$y-y_0=m(x-x_0)$ and we plug in there everything we need.

$y-5=3(x+4) \rightarrow y=3x+12+5\\y=3x+17$

The second is quite similar. This time we want the perpendicular. It means that the product of the slopes has to be -1.

$3\cdot m = -1 \rightarrow m=-\frac13$

At this point we have everything, let's replace and write down the line in a better looking form

$y-5=-\frac13(x+4) \rightarrow y= -\frac13 x -\frac43 +5\\y= -\frac13x -\frac43 +\frac{15}3 \rightarrow y= -\frac13x +\frac{11}3$
