Hi there!
From the unit circle, we can locate the two values of sine Ф (y-value of the coordinate) at which sin Ф = √3/2.
The two values are Ф = π/3 and 2π/3.
Answer:
a: 15 in
b:210 cm
c: 21 yds
Step-by-step explanation:
a: to find the area of a triangle multiply the base and the height, then divide the result by two.
b: to find the area of a trapezoid, multiply the median ( the point where the opposite corners cross) and the height.
c: to find the area of a parallelogram, multiply the lenght and the height.
Hope this helps!
Answer:
Step-by-step explanation:
A anything below 5.7
The first question is an application of the law of sines to find a side of the right-hand triangle. You must then recognize that since two of the angles of the triangle on the right are equal, their opposite sides must be equal.
The second question was really similar in the way they wanted you to go about solving it.
