Two of the angles in a triangle measure 21° and 40°. What is the measure of the third angle

119°

Step-by-step explanation:

The total of the interior angles of a triangle is 180° so if you add the two angles you have, you get 61 and just subtract that from 180 to get the missing angle.

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.

6 meters
