0.8 is 20% of what number?

1 answer:

6 0

0.8 is 20% of 4. This is because 20% of something occurs when something is divided by 5, since it is 1/5 of 100. You multiply 0.8*5, and you get 4.

Answer:

$m\angle 1 =60.75^\circ \\m\angle 2 =119.25^\circ$

Step-by-step explanation:

From the diagram:

$m\angle 1 =60.75^\circ $(Corresponding Angles)\\$

Now Angle 1 and Angle 2 are on a straight line, therefore:

$m\angle 1 +m\angle 2 =180^\circ $(Linear Postulate)\\Since m\angle 1=60.75^\circ\\60.75^\circ +m\angle 2 =180^\circ\\m\angle 2=180^\circ-60.75^\circ\\m\angle 2 =119.25^\circ$
