Find the value of x 85 (X + 37) (6x + 22) 69

g100num [7]

Answer:

x = 21°

The angles of the quadrilateral are:

85°
58°
148°
69°

Step-by-step explaination:

The above figure is a quadrilateral.

Hence, the angle sum of the shape is 360°.

Therefore,

$85 + (x + 37) +69 + (6x + 22) = 360$

$85 + x + 37 + 69 + 6x + 22 = 360$

$(85 + 37 + 69 + 22) + (x + 6x) = 360$

$213 + 7x = 360$

$7x = 360 - 213$

$7x = 147$

$x = \frac{147}{7}$

$x = 21$

ra1l [238]

<h2>Answer:</h2>

Sample space = {10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40, 41, 42, 43, 44}

∴ n(S) = 20 .

[i] Let A be the event that the number so formed is a prime number.

∴ A = {11,13,23,31,41,43}

∴ n(A) = 6

So, P(A) = n(A)/n(S) = 6/20

∴ P(A) = 3/10.

[ii] Let B be the event that the number so formed is a multiple of 4.

∴ B = {12,20,24,32,40,44}

∴ n(B) = 6

So, P(B) = n(B)/n(S) = 6/20

∴ P(B) = 3/10.

[iii] Let C be the event that the number so formed is a multiple of 11.

∴ C = {11,22,33,44}

∴ n(C) = 4

So, P(C) = n(C)/n(S) = 4/20

∴ P(C) = 1/5.
