Given that cos75º 0.259, which statement below
is also true?

A. sin15º = 0.259
B. sin75° =0.259
C. sin15º = 0.966
D. cos15° =0.259

Answers

Alright, lets get started.

Please take a look at the diagram attached.

The reference angle of 75 will be 75

As it is mentioned that the angle intersects the unit circle means r = 1

So, finding cos

cos 75 = [tex]\frac{X}{r}[/tex]

cos 75 = [tex]\frac{0.259}{1}[/tex]

cos 75 = 0.259 is the Answer

Hope it will help :)

answer: A. Sin15 = 0.259

Answer:

[tex]\frac{1}{3} * \frac{1}{4} = \frac{1}{12}[/tex]

Step-by-step explanation:

When multiplying two fractions together, you multiply the numerator by the numerator, and the denominator by the denominator. In this case, the numerator would be 1 * 1 = 1, and the denominator would be 3 * 4 = 12, so the correct answer is [tex]\frac{1}{12}[/tex].

A landscape architect used the entire length of an 80-foot rope to lay out a flower bed in the shape of a circle. (Drawings not to scale.)



What is the area of the circle rounded to the nearest square foot?

Answers

Answer:

Step-by-step explanation:

A square has 4 sides so 80/4= 20ft

area= 20^2

area=400 square ft

2*3.14*r = 80

r = 80/6.28

r=12.74 ft

area= A = 3.14*12.74^2

A = 509.6 sq/ft

if you wanted to find the difference:

509.6 - 400 = 109.6 sq/ft more in the circle

Answers

Answer:

5. Both angles are interior angles, and x = 19

6. Both angles are corresponding angles, and x = 16

Step-by-step explanation:

5. Since both angles are interior angles, they add up to 180°, so we need to add them together, say it's equal to 180, and then solve for x.

5x + 9 + 4x = 180

9x + 9 = 180

9x = 171

x = 19

6. Since both angles are corresponding angles, they are both equal to each other, so we set them both equal to each other and then solve for x.

8x - 2 = 126

8x = 128

x = 16

For question number 5, the value of x would be 19 (because 5x+9+4x will add up to 180) and the answer to number 6 would be that the value of x would be 15.5 (because 126=8x-2)
