The proof, with a missing reason, proves that the measure of angle ECB is 54°.
aniked [119]

Answer:

Midsegment of a Triangle Theorem

Step-by-step explanation:

In\: \triangle ADE\\m\angle A + m\angle D + m\angle AED = 180°\\\therefore 90°+36°+m\angle AED= 180°\\\therefore 126° +m\angle AED = 180°\\\therefore m\angle AED = 180°-126°\\\therefore m\angle AED = 54°\\

In\: \triangle ADE, D and E are mid points of sides AB and AC respectively.

Therefore, DE || BC

Hence, by Midsegment of a Triangle Theorem

m\angle ACB = m\angle AED =54°(corresponding\:\angle 's) \\\therefore m\angle ECB = m\angle AED =54°(\because A - E - C)

Maru [420]
To answer this, create equivalent rates of debt to total assets. I would write 71/100 to x/270000. To create equivalent rates, multiply both numerator and denominator by 2700. 71 x 2700 =$191700.
