The three inside angles (a, b and c) of a right-angled triangle are in the ratio 7: 18: 11 the smallest angle is 35 degrees work out angles a, b and c

Therefore the measure of the angles of a right angled triangle ABC are,

Step-by-step explanation:

Let the Common multiple be  ' x '

given the angles are in the ratio 7 : 18 : 11

Therefore the angles are

∠A = 7x , ∠B = 18x  , ∠C = 11x

To Find:

∠A = ? , ∠B = ? , ∠C =?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

  ..Triangle sum property.

Substituting the values we get

substitute ' x ' in the measure angles we get

Therefore the measure of the angles of a right angled triangle ABC are,

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
