What is the x value of the triangle 3x-5, 2x+20, 4x-30

docker41 [41]

<u>Answer:</u>

x = 21.7°

<u>Step-by-step explanation:</u>

We know that the sum of the three angles in triangle add up to a total of 180°.

So adding the given expressions of angles and putting them equal to 180 to find the value of x:

$(3x-5) + (2x+20) +(4x-30)= 180$

$4x+3x+2x+20-30-5=180$

$9x=180+30-20+5$

$9x=195$

$x=\frac{195}{9}$

$x=21.7$

Therefore, the value of x in a triangle with angles 3x-5, 2x+20, 4x-30 is equal to 21.7°.

Answer:

B. 6π $\sqrt{2}$

Step-by-step explanation:

If you look at the help image I attached, what we are given is in RED and what we solve is in BLUE.

First, draw a diagonal in the square. Its length is the diameter, but we don't know the exact value. Since two right triangles have been created, we use Pythagorean Therom to solve for the hypotenuse/diameter:

$a^2+b^2=c^2\\6^2+6^2=c^2$

$\sqrt{36+36} =c$

$6\sqrt{2}=c$

If diameter = $6\sqrt{2}$ , then radius is $\frac{6\sqrt{2}}{2}$ or $3\sqrt{2}$

Circumference = 2πr

2π ( $3\sqrt{2}$ )

6π $\sqrt{2}$

I hope this helps!
