z = 106
y = 74
Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.
To round 389,422 to the ten thousand, you need to go to the second number which is 8 and round it to the right. To the right of 8 is 9 so if a number is more than 5 you round 8 to 9. Then all the numbers after 8 turn into zeros
So... your answer is:
390,000

Answer:
Can you type out the problem? It's hard to read but if you do then I can give you a step by step on how to find it
Step-by-step explanation:
Answer:
Choice A.
Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 = 28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
= 21.407 ft.
