Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°

Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
A. 37/100
b. 736. 3300/160 is 20.215
20.215x37 =
736. hope this helped
I think I can help with a few...
16. They are equal because of distributive property.
18. 12*5 and 3/8 -> 12/1*43/8 -> 516/8 -> 129/2 -> 64.5
19. Everything is right until the last step, where it should be 6 and 2/3.
