Anestetic [448]4 years ago
7 0

Answer:

A = 43°

b = 25.8 (3 sig. fig.)

c = 14.5 (3 sig. fig.)

Step-by-step explanation:

Using angle sum of triangle, we get A = 180 - 104 - 33 = 43°

Using sin law,

b/sin104 = 18.1/sin43

b = 25.8 (3 sig. fig.)

c/sin33 = 18.1/sin43

c = 14.5 (3 sig. fig.)

A living room has a circular rug. According to a small tag, the rug has a circumference of 6.28 yards. What is the rug's area?
cluponka [151]

Answer:

A = 3.14 yd^2

Step-by-step explanation:

The circumference  is given by

C = 2 * pi * r

Letting pi be approximated by 3.14

6.28 = 2 * (3.14) *r

6.28 = 6.28 r

Divide each side by 6.28

6.28/6.28 = 6.28r/6.28

1=r

We can find the area by

A = pi r^2

A = 3.14 (1)^2

A = 3.14

Round your answer to one decimal digit. The volume of a cylinder is 1 800 cm3. If the height of the cylinder is 40 cm then the d
Lunna [17]

Answer:

7.57 cm

Step-by-step explanation:

Volume of a cylinder = πr²h

π = 3.14

r= radius

h = height

1,800 = 3.14 x r² x 40

r² = 1800 /(3.14 x 40)

r² = 14.33121

√14.33121 = r

r = 3.785658 cm

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

Diameter = 2 x 3.785658 cm = 7.57cm

Find tanX if cotX =2
Tom [10]

Answer:

1/2

Step-by-step explanation:

Let's define these trigonometric functions:

- tangent (tan): opposite / adjacent

- cotangent (cot): adjacent / opposite

Basically, tangent and cotangent are reciprocals of each other.

We know that cot(x) = 2. The reciprocal of 2 is 1/2, which means that tan(x) = 1/2.

Thus, the answer is 1/2.
