In a rhombus ABCD, AB-BD then the measure of <ACD andADC are respectively

Answer»

if AB = BD, that is the side of the rhombus is equal to its one of the dialogonals , which means that rhombus if formed by equilateral triangle , having angle A as 60° and other angle as 120°

so, angle ADC = 120°

And angle ACD = 1/2*(Angle A) = 1/2*(60°) = 30°

The present age of father is four times the age of hisson. After 10: years, the father will become threetimes the age of the son. The age of father after 5years will be(C(I

Answer»

Let present age of son = xAge of father = 4x

After 10 yearsAge of son = x + 10Age of father = 4x + 10

Then,4x + 10 = 3(x + 10)4x - 3x = 30 - 10x = 20

Age of father after 5 years= 4x + 5= 4*20 + 5= 85 years

according to triangle sum property, sum of all angles= 180so, 45+75+A= 180120+A= 180A= 180-120A= 60

a+b+ c =180a+45+75=180a=180-120a=60

sum of all angles in triangle =180° : angle A+angle B+angle C=180 x+45+75=180 x+120=180x=180-120x=60angle A=60°

By angle sum property of triangleA + B + C = 180° A + 45° + 75° = 180°A = 180° - 120° A = 60°

The sum of the present ages of a father and his son is 99 years. When the father was old as his son is now, his agewas four times age of the son at that time. The ratio of the present ages of the son and and the father is:(a) 3:7(b) 3 : 8(c) 4:9(d) 4:7

Answer»

f+s=99so s=99-fnow suppose x years ago f-x=99-f so 2f=99+x so f=(99+x)/2so f-x=4(s-x)(99+x)/2=4s-4x99+x=8s-8x99=8(99-f)-9x=99(8)-4(2f)-9x9x-4(99+x)=7(99)9x-4(99)-4x=7(99)so x=27so f=(99+27)/2=126/2=63so s=99-63=36so ration of son to father = 36/63=4:7

(a) A bag contains 4 red, 3 blue and 2 whiteballs. If three balls are drawn one by one(without replacement), what is the probabilitythat all three balls are red?(b) Two dice are thrown simultaneously. Whatis the probability of obtaining a total scoreof 7?

Answer»

Ans :- On a two unbiased dice, there are36(6×6) possible outcomes.

In order to get a sum equal to 7, the outcome from the two unbiased dice should be either of the following:{1,6} {2,5} {3,4} {4,3} {5,2} {6,1}

There are 6 possible outcomes that will result to a sum of 7. So:

=6/36=1/6=0.167=0.167or16.67%

The probability of getting a sum equal to 7 is16.67%.
