Answer:

The length of each side is 26.3 cm

Step-by-step explanation:

Opposite sides of an isoceles triangle are equal

The isoceles triangle is divided into 2 right-angled triangles so the length of one side can be calculated using trigonometric ratio

When the isoceles triangle is divided, the angle in the right-angled triangle is 20° (1/2 of 40°) and the base is 9cm (1/2 of 18 cm), the hypotenuse side is calculated using trigonometric ratio

Let the length of the hypotenuse side be y

9/y = sin 20°

y = 9/0.3420 = 26.3

Length of each side is 26.3 cm

Maria stated that 5/6 is between 4/5 and 6/7<br> Do you agree? Give reasons for your answer.
ira [324]

Answer:

Yes, because look at the below work.

Step-by-step explanation:

Step 1:  Find the Common Denominator

The common denominator is 210

5/6 * 35/35 = 175/210

4/5 * 42/42 = 168/210

6/7 * 30/30 = 180/210

5/6 is between 4/5 and 6/7 because 4/5 = 168/210 which is less than 5/6 which is 175/210 and 5/6 is less than 6/7 which is 180/210.

So, yes I agree with Maria
