When you add the degrees of all the angles in a triangle you should get 180
A= 5x+5
B= 90
C= 3x+5
5x + 3x = 8x
5 + 90 + 5 = 100
8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8
x = 10
Now plug 10 into angles A and C
5(10)+5= 55
3(10)+5= 35
A= 55 , B= 90 , C=35
Using the formula for lines y=mx+b
To find out the gradient of the line, we do (y2-y1)/(x2-x1).
(3-6)/(-1-2)= -3/-3= 1 is the slope of the line
So far, y=(1)x+b
Now substitute one of your given coordinates into this equation:
6=2+b
b=4
Therefore, the equation of the line is y=x+4
841 rounded to the nearest 10th is 840...hope this helps u :)
35%.
42/120 = 0.35.
0.35 X 100 = 35. That tells us 42 is 35% of 120.
