Question

Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of

Answer 1

Answer:

$ADC = 70$

Step-by-step explanation:

Given

$BCA = 50$

$DCA = 60$

See attachment for parallelogram and complete question

Required

Find ADC

From the attachment:

$BCD = BCA + DCA$

$BCD = 50+60$

$BCD = 110$

Adjacent angles add up to 180.

So:

$ADC + BCD = 180$

$ADC = 180-BCD$

$ADC = 180-110$

$ADC = 70$
