Hi DoraTheExplorer36!
In order to solve number 10:

area of a circle : A=pie * radius (r) squared

A=πr2

Radius is half of a circle and diameter is a full line across a circle

Solve :

A=πr2

A= 3.14 * 11 (radius) 2


1193.0116

Rounded to the nearest whole number is : 1193.

Your answer would be 1193.

Hope that helped! :)

URGENT!!! Please answer ASAP with full working out thank you
Tema [17]

Step-by-step explanation:

a) \\  \frac{a}{x - 1}  -  \frac{2}{x + 1}  =  \frac{4}{(x - 1)(x + 1)}  \\  \\  \frac{a(x + 1) - 2(x - 1)}{(x  -  1)(x + 1)} =  \frac{4}{(x - 1)(x + 1)}  \\  \\ a(x + 1) - 2x + 2 = 4 \\  \\ a(x + 1) = 4 + 2x - 2 \\  \\ a(x + 1) = 2x + 2 \\  \\ a (x + 1) = 2(x + 1) \\  \\ a= \frac{2(x + 1)}{(x + 1)}  \\  \\  \huge \red{ \boxed{a = 2}}

Solve b part yourself in the same way.

An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression. To the nearest foot, how far is the boa
Yuri [45]

Answer:

407.22 foot is the boat from the base of the lighthouse

Step-by-step explanation:

Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.

Let x foot be the distance of the object(boat) from the base of the lighthouse

Angle of depression = 7^{\circ}

\angle CAB = \angle DCA = 7^{\circ}       [Alternate angle]

In triangle CAB:

To find AB = x foot.

Using tangent ratio:

\tan (\theta) = \frac{Opposite side}{Adjacent Base}

\tan (\angle CAB) = \frac{BC}{AB}

Here, BC = 50 foot and \angle CAB =7^{\circ}

then;

\tan (7^{\circ}) = \frac{50}{x}

or

x = \frac{50}{\tan 7^{\circ}}

x = \frac{50}{0.1227845609}

Simplify:

AB = x = 407.217321 foot

Therefore, the boat from the base of the light house is, 407.22'

The lengths of the sides of triangle ABC are represented in terms of the variable m, where m > 6.
Evgen [1.6K]

Answer: List of the angles from smallest to largest are C, B and A

Step-by-step explanation:

The diagram of triangle ABC is shown in the attached photo. Since none of the sides are equal, then it is a scalene triangle.

From the information given,

AB = m – 2

BC = m + 4

AC = m

It means that the longest side is BC, the medium side is AC and the shortest side is AB. Therefore,

The smallest angle is angle C.

The medium angle is angle B.

The largest angle is angle A
