How to do 2,3,5,7,11 equal 111

2*5*(3+7)+11=111

Step-by-step explanation:

You can combine the numbers using operations like adding and multiplication.

I need to produce the 111. Since it's not an exact multiple of the other numbers, I make it as a sum. Thus 100+11=111. I used the 11.

Now I have to produce the 100 with the rest of the numbers.

I see a pair of numbers add up 10: 3+7=10

Thus I produce the other 10 by multiplying 2*5=10

Summarizing, the combination to make the result equal to 111 is

2*5*(3+7)+11=111

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
