We can use the law of sines, which relates the angles and sides of a triangle.
The formula is:
,
where A, B, and C are angles and a, b, c are side lengths.
Let's find the missing angle. The interior angles of a triangle add up to 180 degrees, so the missing angle is 180-70-40 = 70 degrees.
Let's make a proportion and use the two 70 degrees angles and their opposite lengths. Since both sides have the same numerator of 70 degrees, we can equate the denominators together.

Answer:
B. 2 boxes.
Step-by-step explanation:
Area of the floor = 7 1/2 * 8 5/6
= 15/2 * 53/6
= 265/4 feet^2.
Now we divide this are by 1 square foot giving a total of 265/4
= 66.25 tiles
so she needs 2 * 45 tiles boxes (answer).
Answer:
C. The x-coordinate should be Three-fourths.
Step-by-step explanation:
Since point A is 0.75 units to the right, it is 3/4 if 4/4 is 100.
