Supplementary angles always add up to 180. So you need to subtract 30 from 180. Which would give you 150. So 150 is your answer!

150 degrees. Supplementary angles are two angles that, when added together, equal 180 degrees. Simply subtract 30 from 180 and you'll be left with 150, the measurement of the other angle.

Oksi-84 [34.3K]

Answer:

−2=−2x^3

Step-by-step explanation:

10x3= 3x2−20x−6=(10x3⋅(3x2))(−20x−6)=−600x6−180x5x2=−600x6−180x5−2x⋅(2x2)=−4x3−2x⋅x2=−2x^3

−2=−2x3

2x^2=−2x^3

−2=−2x^3

60% expressed as a ration is StartFraction 60 Over 100 EndFraction. What is this as a fraction in its reduced form?
Leno4ka [110]

Answer:

3/5

Step-by-step explanation:

60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.

Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)

6/10 = 3/5  [divide both numerator and denominator by 2)

So, the reduced form of 60% =3/5
