Answer:
∠1=128°
∠2=52°
∠3=47°
∠4=133°
∠5=81°
Step-by-step explanation:
6.
∠1=180-52=128°
∠2=52°(alternate angles)
∠4=180-47=133°
∠3=47°(alternate angles)
∠2+∠3+∠5=180
52+47+∠5=180
∠5=180-99=81°
Answer:
Mean of a grouped data is
Sum of F x/ sum of frequency F
Sum of F = 5 + 15 + 13 + 10 + 7 = 50
to find x find the average of the two classes
That's
0 + 10/2 = 10/2 = 5
10+20/2 = 15
20 + 30 / 2 = 25
30+40 /2 = 35
40+ 50 / 2 = 45
Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)
= 1240
Therefore
Mean = 1240/50
= 24.8cm

Answer:
D. 15
Step-by-step explanation:
Given the expression, 32 + 2n - 9, and a value of <em>n </em>= -4:
You can substitute the value of <em>n</em> into the given expression:
= 32 + 2n - 9
= 32 + 2(-4) - 9
= 32 - 8 - 9
= 15
Therefore, the correct answer is D. 15
