Answer:
221°
Step-by-step explanation:
Using sine rule
a/sinA = b/sinB = c/sinC
A= 36°
B= 37°
C = 107°
It takes 90 seconds to go from point A to point B. To find a, we will use
a/sinA = c/sinC
a/sin36°= 360/sin 107°
a(sin 107°) = 360sin36°
a = 360sin 36° / sin 107°
a = 360(0.5878) / 0.9563
a = 211.608/0.9563
a = 221.27°
a = 221°
<h3>The length in standard notation is 0.05 meter</h3>
<em><u>Solution:</u></em>
Given that,
Jeremy measured the length of an ant as
We have to write the length in standard notation
From given,
Thus the length in standard notation is 0.05 meter
<em><u>Method 2:</u></em>
Use the exponent of 10 to determine how many places to move the decimal point
Since exponent is -2, is negative
Thus, we have to move the decimal point to right 2 places
Thus the length in standard notation is 0.05 meter
