To round to 3 sign. fig. you have to look at your fourth figure, is it between 0-4? If yes, then it´s should be rounded down. Is it between 5-9? If no, then it´s should be rounded up.
Now, in this case the fourth figure is 4, meaning it should be rounded down..
198 is therefore your answer:D
Have a nice day

Answer:
B) 74
Step-by-step explanation:
This is an icoseles triangle because of the 2 lines in each side. This makes <Y equal to <Z
Given:
<Y = <Z
All triangle angles add up to 180 so:
<W + <Y + <Z = 180
<W + 53 + 53 = 180
<W + 106 = 180
<W = 180 - 106
<W = 74
