Make a ratio:
2:3, 2 being the yellow straw and 3 being the red straws
They are now asking how many red if there are 30 yellow straws
2:3 = 30:x
You could either cross multiply or simply do 30 ÷ 2 = 15 then 15 × 3 = 45. Your answer is 45
<u>Cross </u><u>multiplying</u>
2x = 90
90 ÷ 2 = 45

Note that the measurement of the supplementary angles when combined will equal 180°. To find the other angle, simply subtract the angle measurement given from 180:
4. 80°
180 - 80 = 100°
100° is the supplementary angle.
5. 65°
180 - 65 = 15°
15° is the supplementary angle.
6. 34°
180 - 34 = 146°
146° is the supplementary angle.
