Answer:
Therefore the two supplementary angles are 40° and 140°.
Step-by-step explanation:
Given:
Let the measure of one angle of supplementary be 'x'
Then according to the given condition the other angle will be '3.5x'
To Find:
x = ?
3.5x = ?
Solution:
Supplementary angles:
Supplementary angles are those angles whose sum is 180°
We have two angles 'x' and '3.5x'
∴
one angle is 40°
Another angle will be
Therefore the two supplementary angles are 40° and 140°.
Answer:
The number of ways Tony and Maria can both be selected for the committee is 8 ways.
Step-by-step explanation:
i) Tony and Maria have to be on the committee together or not at all.
ii) Let us consider Tony and Maria as combined as one person.
Therefore now we can say that the number of eligible people for the committee = 9 - 1 = 8.
iii) therefore the number of ways that both Tony and Maria can be selected for the committee are
= 8C1 =
