If AB=4 feet & AD=10 feet & m What is DC?
What is BD?
What is m What is m

1. DC = AB = 4 ft

2. BD = 10.80 ft

3. m<CED =

4. m<EBC =

Step-by-step explanation:

From the given quadrilateral,

Given: AB = 4 ft, AD = 10 ft and m<BAE = 65.

1. DC = AB = 4 ft (opposite sides of a parallelogram are equal)

2. Applying the Pythagoras theorem to ΔABD, we have;

= +

= +

       = 16 + 100

       = 116

BD =

     = 10.7703

BD = 10.80 ft

3. m<CED = (the diagonals bisects each other at right angle)

4. m<ABC + m<BAC + m<ACB = 180

90 + 65 + m<ACB = 180

m<ACB = 180 - 155

m<ACB =

So that,

m<BEC + m<EBC + m<ECB = 180

90 + m<EBC + 25 = 180

m<EBC = 180 - 115

m<EBC =

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
