In ΔABC, the measure of angle A is 5° more than 3 times the measure of angle B. Angle C measures 20°less than angle B. Determine the measures of angles A, B, and C.

A = 122°, B = 39°, C = 19°

Step-by-step explanation:

(5+3B) + B + (B-20) = 180

5B = 195

B = 39°

A = 5 + 3(39) = 122°

C = 39 - 20 = 19°

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
