(b) Out of 200 students in an examination of class IX, 140 passed in Maths, 120 passed in Scien

iren [92.7K]

Answer:

n(U)=200

n(M)=140

n(S)=120

n(MuS)complement=40

n(MuS)=n(U)-n(MuS)complement

=200-40

=160

n(MnS)=n(M)+n(S)-n(MuS)

=140+120-160

=260-160

=100

Mhanifa please help fast

Shkiper50 [21]

Answer:

a is supplementary with 36 and b is supplementary with 113.

a = 180 - 36 = 144
b = 180 - 113 = 67

Correct choice is D

LM = 1/2(AB + DC) = 1/2(46 + 125) = 85.5

Diagonals of a rectangle are congruent

KM = LN
6x + 16 = 49
6x = 33
x = 33/6
x = 5.5

Correct choice is A

Find the missing side<br> 13 ft<br> 5 ft <br> x

Scilla [17]

Answer:

Assuming you're referring to the sides of a right triangle, the missing side X would be 12.

Step-by-step explanation:

The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. $13^{2}$ is 169, $5^{2}$ is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.
