B. 25 Km. The measure of BC is 25 km.
The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.
BC = √AC²+AB²-2(AC)(AB)*cos A
BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°
BC = √441km²+196km²-588km²*(0.017)
BC =√637km²-10.26km²
BC = √636.74km²
BC = 25.03km ≅ 25
Answer:
61.27 cm
Step-by-step explanation:
(3.14)(11)(0.5) = 17.27
2+2+20+9+11+17.27 = 61.27
2x-3+7x-10=32
9x-13=32
9x=32+13
9x=45
x=5
Answer:
See the diagram for understanding
Step-by-step explanation:
Suppose the woman at point A and moves towards east . But the point A is at the south and she is moving upwards towards east according to the compass. That is why this statement is incorrect .
In the compass it would be east but she has to move north to reach east. There's a difference between the actual position the direction of movement of the person to reach that position.
This is better explained by the following diagram.
Now we can see she will move along line B , C and D to reach east which are actually to the north of her position. So the given statement is false.
