Answer:
22
Step-by-step explanation:
m1 + m2 = 180
3x - 17 + 5x + 21 = 180
3x + 5x + 21 - 17 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176 / 8
x = 22
A° = 1/2 (90) = 45°
b° = 1/2[360 - (110 + 90)]
b° = 1/2(160)
b° = 80°
a° + b° = 45° + 80° = 135°
Answer
135°
25 % = 18
50% = 36
75 % = 54
100 % = 72
25% x 72 = 18 therefore n = 72
125% x 72 = 90
Therefore 125% of n is 90
<span>the numbers of first 8 beads which are white are
1,5,9,13,17,21,25,29
think of it as an arithmetic progression here the first term will be 1 cause white was first bead then after 3 blue beads another white added soits position is fifth now the difference would come out as 5-1=4 so now position of next white bead could be predicted by nth term formula of an AP which a+(n-1)d here a is first term which in this case is one and d is difference which here is 4
So nth bead position is 1+(n-1)4</span>
