Step-by-step explanation:
The given sample space of S is = {ABC, ABD, ACD, BCD},
And from this sample space it can be deduced that;
(a) There can be four ways to choose the committee.
(b) There can be three ways in which person D is always included.
(c) And if persons B and C are necessarily be included, then there are two ways to form the committee.
Answer:
m∠CBD=68°
Step-by-step explanation:
BA is perpendicular to BD, meaning they form a right angle (90°)
This means m∠CBD + m∠ABC=90, or they are supplementary.
We have expressions given for these angles, so
4x+52+8x-10=90
12x+42=90
12x=48
x=4
Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.
4(4)+52=68
m∠CBD is 68°.
I believe it should be at least a B- 80% or higher is a B
