Check the attached file for the picture of the said angle.

Since DB and DC are angle bisectors, they cut the other angle into two equal parts.

Since DCB is equal to 40 degrees, so we can say that ACB is 80 degrees.

Triangle degrees = BAC degrees + ACB degrees + ABC degrees

180 = 60 (given) + 80 + ABC degrees

40 degrees = ABC

Since DB bisects ABC = 40/20 = 20

Answer would be 20 degrees.

Answer:

The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.

The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.

The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:

No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).

If a=12 and 120% of a is equal to 80% of b then what is a+b
mojhsa [17]
A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18

a+b = 12 + 18 = 30

fiasKO [112]
The penny will fall 112 feet the fourth second, 144 feet the fifth second, and 176 feet the sixth second. Therefore, the penny will be a total of 576 feet from the cliff at six seconds.
