In triangle abc, the measure of angle b is 20 more than three times the measure of angle
sleet_krkn [62]
Let x be the degree of angle a. 

Angle b: 20+3x
Angle c: 55+x 

We know that all angles add up to 180 degrees. 

180=x+(20+3x)+(55+x) 
180= 5x+75 
180-75=5x 
105/5=x
21=x 

Angle a: 21 degrees 
Angle b: 20+3(21) => 83 degrees 
Angle c: 21+55 => 76 degrees 

Hope I helped :)

What is the distance between the points (-4,2) and (3,-5)
34kurt

Answer:

7√2 units

Step-by-step explanation:

The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

\sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

Here, x1=-4 and y1=2

x2=3 and y2=-5

\sqrt{ {(3  - ( -  4))}^{2}  +  {( - 5 - 2)}^{2} }

\sqrt{ {(3 + 4)}^{2}  +  {( - 7)}^{2} }

\sqrt{ {(7)}^{2}  +  {( - 7)}^{2} }

\sqrt{49 + 49}  = 7 \sqrt{2}
