Answer:

Step-by-step explanation:

10) ∠2 + 41 = 180 {Linear pair}

∠2 = 180 - 41

∠2 = 139

11) ∠3 = ∠2 {Vertically opposite angles}

∠3 = 139

12) ∠4 = 41 {Vertically opposite angles}

Answer:

If you look at the different triangles in the star they give you two angles....

all of the points in a triangle would be equal and you just subtract 24 from 105

x is 24 and y is 81

How can I find a? (Trigonometric Ratios)

earnstyle [38]

Step-by-step explanation:

Hey there!

Use cos ratio to find the value of 'a'.

As per given, we can state that it is a Right angled triangle, so taking 38° reference angle.

We get;

p = AC

b = 6

and h= a

Here, Use the value of b, h and 38° angle to find the value of a.

$\cos(38° ) = \frac{b}{h}$

$\cos(38°) = \frac{6}{a}$

$0.7881 = \frac{6}{a}$ [ cos(38°=0.7881]

$0.7881a = 6$

$a = \frac{6}{0.7881}$

Therefore the measure of a is 7.61 Or 8.

Hope it helps..

How to solve inscribed angles

alisha [4.7K]

If it involves an Arc, the inscribed angle is 1/2 of the measure of the are across from it. If the figure inscribed in a quadrilateral, opposite angles are supplementary (when added together equals 180 degrees) This is all I know :)

Consider an airplane heading due east at 150 miles/hour relative to the air. The wind is blowing at 7.1 miles/hour at 45º south

sergij07 [2.7K]

We have

Va(airplane)=150 East

Vw(wind)=7.1 South East

resulting vector R

airplane

Vax=150 Vay=0 it only has component x

Wind
Vwx=7.1*cos45=5.02

Vwy=7.1*sin45=-5.02 is negative because is South direction

|R|=(Rx^2+Ry^2) ^0.5

Rx=150+5.02=155.02

Ry=0-5.02=-5.02

|R|=155.10 miles/hour South East

Determine angle θ

Rx=R*cos(θ)

Cos(θ)=Rx/R Cos(θ)=155.02/155.10=0.9995

θ =arc cos Rx/R θ =1.8119 º

Rx represents the component in the East direction of the resultant force. Your contribution is given by both, the force of the plane and the wind. The contribution of the wind makes the airplane's speed greater

Ry represents the component in the South direction of the resulting force Its contribution is exclusive of the wind since the airplane has no component in this direction

|R| the force resulting from the combined action of the force of the plane and the force of the wind

θ represents the angle that forms the resultant force with respect to the x axis or east direction

Which answer choice shows 3.002 written in expanded form?A) 3 + 0.2B) 3 + 0.02C) 3 + 0.002D) 3+ 0.0002

Elanso [62]

SOLUTION

We want to know which answer choice shows 3.002 written in expanded form

To do this let us subtract 3.002 from 3, we have

We got 0.002

So the expanded form is
