Use the figure to identify each pair of angles as complementary angles, supplementary angles, vertical angles, or none of these.
a. angles 1 and 5
b. angles 3 and 5
c. angles 3 and 4

(a) Complementary angles

(b) Vertical angles

(c) Supplementary angles

Explanation:

Complementary angles are those two angles whose sum is 90 degrees.

Supplementary angles are those two angles whose sum is 180 degrees.

Vertical angles are the angles opposite each other when two lines cross.

(a)

Angles 1 and 5 are complementary angles

(b)

Angles 3 and 5 are vertical angles

(c)

Angles 3 and 4 are supplementary angles

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

yes. we do proportions in probabilities.
