What is the complement and supplement angel of 20

70° and 160°

Step-by-step explanation:

Assuming you mean the complement and supplement for 20°

Complement is angles that add up to 90° (so 90° - 20° = 70°)

Supplement is angles that add up to 180° (so 180° - 20° = 160°)

The complement angle is 70

The supplement angle is 80

Step-by-step explanation:

Complement angles always equal 90

90-20=70

The measure of a supplement angle is 20 degrees more than 3 times the original angle

20*3=69

60+20=80

Hope this helps :)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

6 cm
