Question

ABCD is a rectangle find each value

Answer 1

Explanation:

for angle <ADB= 90-31= 59 degrees

for angle <ACD= ACD have the same shape like BDC so it will be 31 degrees

for angle< DBC= remember ADB and ABD are same so the angle ADB is equal to ABD. So it is 59 degrees.

for angle<DEC= Add both angles C and D 31 and 31.

so

<DEC+31+31=180

<DEC+62=180

<DEC=180-62

<DEC= 118DEGREES
