Answer 1

Answer:

(a)

Step-by-step explanation:

(a)110°+x+x=180°(Angle Sum Property)

=>110°+2x=180°

=>2x=180°-110°

=>2x=70°

x=70°/2

x=35°

So ∠A and ∠B=35°

(b) To arrange the fractions in ascending order, the denominators should be same but they are different, so we have to find the LCM of 5, 10, 15 and 20 which are the denominators

L.C.M. of 5, 10, 15 & 20=60

Now, we will multiply the fractions with a number so that the denominator become 60

We will get the numbers 36/60, 54/60, 28/60, 51/60

*Remember to also multiply the numerator by the same number you are multiplying the denominator

Now, we can arrange these in ascending order

28/60, 36/60, 51/60, 54/60

Now write the original number according to the above order:-

7/15, 3/5, 17/20, 9/10
