B. Given that BC = DC and AB CB, AD CD.
Find the following given their measurements

1. m<BAC = (4x+18)°; m<DAC = (2x+30)
a. x
b. m<BAC
c. m<DAC

2. BC = 7x - 8; DC = 4x+4
a. x
b. BC
c. DC

3. m<BAC = (6x+5)°; m<DAC = (2x+45)°
a. x
b. m<BAC
c. m<DAC

4. Find m<ADC

(Please answer it properly po. I (we) need this by morning, thank you^^)​
