In this figure, 4 is an exterior angle to triangle VAUL. (A) What is the angle measurement of angle 3? Explain the angle relationship you used.

(B) What is the angle measurement of angle 4? Explain the angle relationship you used.

(C) What is the angle relationship between angles 3 and 4?
What is the angle relationship between angles 1, 2, and 3?
What do you notice that is similar between the two?
What is different?

(D) Which two angles in the triangle equal angle 4? Use your work from part c to figure out why this is the case, and explain your conclusion.

positive

step-by-step explanation:

the quadrant is facing upwards

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
