Mathematics

Answer:

Step-by-step explanation:

Angles a and b are opposite, so they are equal. The same is true for angles O and 3b.

So, the four angles are actually (starting from the left and going clockwise) 3b,b,3b,b

These four angles sum up to 360, so we have

3b+b+3b+b =8b = 360 \iff b = \dfrac{360}{8} = 45

And since a and b were the same, a is also 45 degrees.

It wont let me post a picture of the angles but they are verticle angles and the equations are (3x+8), (5x-40) and it says find
____ [38]
Vertical angles are equal

5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24

m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°

(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)

Find equation of a line that has point ( 1, -2 ) and slope -4
Colt1911 [192]
∵It slop=-4
∴Equation is: y=-4x+b
∵Point (1,-2) in this line
(∴We can substitute x, y to 1, -2)
∴-4×1+b=-2
∴b=2
Equation: y=-4x+2
