State the Q1,Q2,Q3,range of 20,40,60,80 and interquartile range

Range=highest - lowest

80-20=60

Similarly

Q1=N/4=15

Q2=60/2=30

Q3=3*60/4=45

Interquartile range=Q3-Q1=45-15=30

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
