Using the Law of Sines (sinA/a=sinB/b=sinC/c) and the fact that all triangles have a sum of 180° for their angles.
The third angle is C is 180-53-17=110°
27/sin53=b/sin17=c/sin110
b=27sin17/sin53, c=27sin110/sin53
And the perimeter is a+b+c so
p=27+27sin17/sin53+27sin110/sin53 units
p≈68.65 units (to nearest hundredth of a unit)
Answer:
Answer choice A(57%)
Step-by-step explanation:
The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)
Answer:
60/100
Step-by-step explanation:
We know that 20 goes into 100 5 times, so we multiple numerator and denominator by 20 to get an equivalent fraction:

Hey there!
If you ever see the word "is" in a story problem, it means that there is an equal sign there. Let's apply that to this.
23800 =(is) 0.34i (income)
Now, we can solve for i by dividing.
23800/0.34= 70,000
Therefore, the annual income is $70,000.
I hope this helps! Have a great day!
