P-Q-R and l(PQ) = 3√2, l(PR) = 5√2

TO DETERMINE

l(QR)

EVALUATION

Here I is REPRESENTING d

Here it is given that : P-Q-R

So Q is the point between P and R

Here it is also given that

l(PQ) = 3√2, l(PR) = 5√2

Hence

$\sf{I(QR) = I(PR) -I(PQ) \: \: }$

$\implies \sf{I(QR) = 5 \sqrt{2} -3 \sqrt{2} \: \: }$

$\implies \sf{I(QR) = 2 \sqrt{2} \: \: }$

Answer»

Answer:

Option D,

3:8

Step-by-step explanation:

Area of TRIANGLE ABC = 1/2 x 6 x 8 = 24 sq.units

Area of triangle ABD = 1/2 x 10 x BD = 24

BD = 4.8

AP= 6 - 4.8 = 1.2

QC = 8 - 4.8 =3.2

AP/QC = 1.2/3.2 = 3/8

Answer» The co-interior ANGLES are always 180° given angle B = 100 angle B + angle C = 180° so ,180 - 100 = 80 ° angle C = 80° The OPPOSITE angles of a PARALLELOGRAM are equal i.e, angle A = angle C = 80° angle B = angle D = 100° 80° + 80° = 160° Hence, the answer is 160°

30.

In the given figure, ABCD is a parallelogram. If ∠B = 100°, then find the value of ∠A +∠C.

Answer»

The co-interior ANGLES are always 180° given angle B = 100

angle B + angle C = 180°

so ,180 - 100 = 80 ° angle C = 80°

The OPPOSITE angles of a PARALLELOGRAM are equal

i.e,

angle A = angle C = 80°

angle B = angle D = 100°

80° + 80° = 160°

Hence, the answer is 160°

31.

Solution of the system of linear equations 3x - 2y = 0, 2x + y = 7 is

Answer»

ANSWER:

$3x - 2y = 0$

$= 3x = 2y$

$= x = \frac{2}{3} y$

$2x + y = 7$

$= 2( \frac{2}{3} y) + y = 7$

$= \frac{4y}{3} + y = 7$

$= \frac{4y + 3y}{3} = 7$

$= 7y = 7 \times 3$

$= y = \frac{21}{7}$

$y = 3$

$x = \frac{2}{3} y = \frac{2}{3} \times 3 = 2$

$So, \: x = 2 \: and \: y = 3$

The product of two numbers is 210 and their HCF is 1.what is their LCM

Answer»

The formula for finding LCM in this QUESTION is

=> 1st no. * 2nd no. = LCM * HCF

=> 210 (Given in question) = LCM * 1 (Given in question)

=> LCM = 210/1 (TRANSPOSED 1 from LHS)

=> LCM = 210

In other words, whenever HCF of 2 numbers is 1, then their product will be the LCM.
