Answer:

The three angles of a triangles are 90° , 45°, 45°

∠A =  90° , ∠B = 45° and ∠C = 45°

Step-by-step explanation:

<u>Explanation</u>:-

<u><em>Step(i)</em></u>:-

The sum of measures of three angles of any triangle is equal to 180°

<em>Let A , B , C be the  angles of the triangle.</em>

<em>∠A +∠B +∠C = 180°</em>

Given data a triangle has angles measuring 2x°, x° and x°

<em>2x°+ x° + x° = 180°</em>

<em>4x° = 180</em>

<em>x° = </em>\frac{180}{4} = 45<em />

x = 45°

<em><u>Step (ii)</u></em><u>:-</u>

Given data  2x = 2 × 45 = 90°

                      x = 45°

and                x = 45°

The three angles of a triangles are 90° , 45°, 45°

∠A =  90° , ∠B = 45° and ∠C = 45°

<u>Final answer</u>:-

The three angles of a triangles are 90° , 45°, 45°

∠A =  90° , ∠B = 45° and ∠C = 45°

Tan 45°. tan² 30° tan 60° <br>slove it​
makvit [3.9K]

Answer:

\frac{\sqrt{3} }{3} or \frac{1}{\sqrt{3} }

Step-by-step explanation:

We can break the problem into three parts,

tan45 = sin(45)/cos(45)=\frac{\frac{\sqrt{2}}{2} }{\frac{\sqrt{2}}{2} } =1

tan^{2}30 =(tan30))^{2}=(sin30/cos30)^2=((1/2)/(\sqrt{3}/2))^2 =(1/\sqrt{3})^2

tan60=sin60/cos60=\frac{\sqrt{3}/2 }{1/2} =\sqrt{3}

Then, tan45*tan^230*tan60=1*(1/sqrt(3))^2*sqrt(3)=1/sqrt(3)=sqrt(3)/3

Therefore, the solution is sqrt(3)/3

Find the equation of the plane passing through the points
erica [24]

Extract the normal vectors from the given planes:

-2x+y+z+2=0\implies\vec n_1=(-2,1,1)

x+y-3z+1=0\implies\vec n_2=(1,1,-3)

(which are unique up to their signs, meaning either \vec n_1 or -\vec n_1 are valid choices for the normal vector)

The third plane must be perpendicular to both these given planes, which means it would be parallel to both \vec n_1 and \vec n_2, which in turn means its own normal vector \vec n_3 should be perpendicular to both \vec n_1 and \vec n_2.

Enter the cross product:

\vec n_3=\vec n_1\times\vec n_2=(-4,-5,-3)

or (4, 5, 3), which also works.

The given plane passes through (-1, 1, 4), so its equation is

(x+1,y-1,z-4)\cdot\vec n_3=0

Simplify:

(x+1,y-1,z-4)\cdot(4,5,3)=0

4(x+1)+5(y-1)+3(z-4)=0

\boxed{4x+5y+3z=13}

A bag contains 4 red marbles and 1 yellow marble. What is the probability of drawing a red marble, then replacing that marble, t
ki77a [65]

Answer:

16/25

Step-by-step explanation:

We have 4 red marbles and a total of 4 + 1 = 5 marbles.

Probability is simply (# times a specific event can occur) / (# times any event can occur).

Here, the probability of drawing a red marble is: 4/5 (because there are 4 red marbles to choose from and a total of 5 marbles to choose from).

We replace the marble afterward, so the probability that the second pick is also red would still be 4/5.

Then, multiply the two fractions together: (4/5) * (4/5) = 16/25.

Hope this helps!
