Answer:
The angles do not have the same reference angle or the same sign.
Step-by-step explanation:
Given:
Statements related to the angle and the quadrant.
To Find:
Which statement gives best explanation
Solution:
Statements are follows:
1)The angles dont have same reference angle:
This statement is not totally true because some angles may have same reference angle . i.e depending upon the quadrant reference angle are founded .
2)Tangent is positive in second quadrant and negative in 4th quadrant:
Above half statement is false because tangent is positive in 3rd and 1st quadrant and negative in rest of quadrant.
3)Tangent is negative in 2nd quadrant and positive in 4th quadrant :
Similarly it is half negative as tangent is positive in 3 and 1 quadrant only.
4)The angles dont have same reference angle or the same sign.
This statement is true in terms of sign because reference angle will not have same sign .this gives best explanation.
Answer:
40
Step-by-step explanation:
by using similar triangles;
27/24=45/x
x=45x24/27=40
Answer:
D. Similar, AA similarity, ΔSCD
Step-by-step explanation:
CD and RQ are parallel. Therefore, ∠Q and ∠D are corresponding angles, and ∠R and ∠C are also corresponding angles. Corresponding angles are congruent.
Therefore, by AA similarity, ΔSRQ ~ ΔSCD.
Answer:
It is stratified random sampling.
Step-by-step explanation:
Stratified random sampling is a method of sampling that involves the division of a population into smaller sub-groups known as <em>strata.</em>
The strata are formed based on members' shared attributes or characteristics, in this case their race.
Stratified random sampling is also called <em>proportional random sampling</em> or <em>quota random sampling</em>
