Answer: divide the numerator(top) by the denominator (bottom) then multiply the answer by 100. Hope this helps!
Answer:
Step-by-step explanation:
x represents the hypotenuse of that right triangle. The reference angle is 52 and is opposite AB, the side which we need to find. The trig ratio that uses the hypotenuse and the side opposite the reference angle is the sin ratio, namely:
and
7,7sin52 = AB so
AB = 6.07 m
Answer:
B. 171
Step-by-step explanation:
Answer:
<h3>AB ≈ 70m</h3>
Step-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
