Answer and Step-by-step explanation:
θ
pi r 
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
1 whole thing = 6 sixths
3 whole things = 18 sixths
1 third of a whole thing = 2 sixths of it
3 wholes plus 1 third = 18 sixths plus 2 sixths = 20 sixths
Answer:
Mr Doyle washed the most.
4/15 still need to be washed.
Step-by-step explanation:
2/5=6/15 Mr Doyle
1/3=5/15 Son
so Mr Doyle washed the most.
Together they washed 11/15 of the laundry so 4/15 is left to wash.
