Answer:
hello mate!
Step-by-step explanation:
1st Question isn't clear
2.)The measure of each angles,
1 angle = x.
the other and the larger angle is 4 times the smaller.
so, 4x.
x° + 4x° = 90°
5x° = 90°, x= 90/5°, x= 18°
smallest Angle measures = 18°
Largest angle measures = (4×18)°= 72°
C.)Kindly, Upload the figure.
d.)The perimeter of a square= 4S = 20m
1 side,/ Measure of its length = 20/4.
1 side =5m.
then, area of The square = S²= 5²= 25m².
E.)The first 7 whole Numbers, = 0, 1, 2, 3, 4, 5, 6.
hence,
The arithemtic mean= sum of Total Numbers / Total Number.
(0+1+2+3+4+5+6)/7= 21/7= 3.
F.)Mode of the Given Number Series,
4,6,8,4,10,4,6,12,6,10.
10=2; 6=3; 4=3; 8=1; 12=1;.
Mode of this series is,
6 and 4.
G.)25m² is the area of the Traingle,
traingle Area's = 1/2×Base×Height.
1/2×Base=20m× (H)m.
20Hm²/2= 25m². (20H)m²=25m²×2
20H = 50, H= 50/20. H=5/2m.
Height of the Triangle = 5/2m
H.)as it is already in ascending order,
I don't need to arrange it.
4,8,12, (16,20), 24,28,32.
Median = (16+20)/2= 36/2= 18.
Thank you mate!
Have a great day ahead!
