Find the value of x. Round the length to the nearest tenth.

STALIN [3.7K]

Answer:

x = 5.13 yards to the nearest tenth

Step-by-step explanation:

The diagram is redrawn and labelled in the attached photo.

It is labelled as triangle ABC. Angle A is determined to be 25 degrees. This is because it is alternate to 25 degrees at the top.

To find x, we will apply trigonometric ratio

Tan # =opposite side / adjacent side

Where # = 25 degrees

Opposite side = x

Adjacent side = 11

Tan 25 = x/11

x = 11tan25

x = 11× 0.4663

x = 5.1293 yards

x = 5.13 yards to the nearest tenth.

A circle has its center at (1, 4) and a radius of 2 units. What is the equation of the circle?

Levart [38]

Answer:

$(x-1)^2+(y-4)^2=4$ .

Step-by-step explanation:

So the standard form of a circle is $(x-h)^2+(y-k)^2=r^2$ where (h,k) is the center and r is the radius.

You are given (h,k)=(1,4) and r=2.

So we are going to plug in 1 for h, 4 for k, and 2 for r:

$(x-h)^2+(y-k)^2=r^2$

$(x-1)^2+(y-4)^2=2^2$

$(x-1)^2+(y-4)^2=4$ .

Solve 3(x + 2) > X.

Tomtit [17]

Answer:

x > -3

Step-by-step explanation:

3(x + 2) > X.

⇒ 3x+6 > x

⇒3x+6-x > x - x [subtract x from both sides]

⇒2x + 6 > 0

⇒2x + 6 - 6 > -6 [subtract 6 from both sides]

⇒2x > -6

⇒x > -6/2 [Dividing both sides by 2 ]

∴ x > -3
