Solve for x. enter your answer in the box. x =

This is an equilateral triangle, a triangle that has 3 congruent/equal sides and 3 congruent angles.

A triangle is 180°, so the three angles should add up to 180°.

Since you know this triangle has 3 equal angles, each angle should be 60°

(60° + 60° + 60° = 180°)

To find x, you can do:

(25x - 15) = 60     (because you know each angle is 60°)

To isolate x, you can first add 15 on both sides

25x - 15 + 15 = 60 + 15

25x = 75      Divide 25 on both sides

x = 3

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
