Answer:
528
Step-by-step explanation:
Find 0.8% of 66,000
Do this through the proportional method.
x = unknown value
0.8% / 100
=
x / 66,000
Cross multiply
66,000 x 0.8
52,800
Now, since a percent is always over a 100, divide it by 100.
52,800/100
To find angle B we use tan
tan ∅ = opposite / adjacent
From the question
AC is the opposite
BC is the side adjacent to angle B
So we have
tan B = AC / BC
tan B = 6/9
tan B = 1/3
B = tan-¹ 1/3
B = 18.43°
B = 18° to the nearest hundredth
Hope this helps you
