The Pyraminx is a Rubik's cube-type toy in the shape of a tetrahedron. The Pyraminx shown below has edges 15\,\text{cm}15cm long

____ [38]

Answer:

8.727

Step-by-step explanation:

Since the below edge, d = 15 cm, and the height, h = 12.2 cm, we will use the Pythagorean theorem to find the distance r.

$d^2=r^2+h^2$

$(15)^2 = r^2+(12.2)^2$

$r^2 = (15)^2-(12.2)^2=225-148.84=76.16$

$r=\sqrt{76.16}=8.727$

Find the value of x........

raketka [301]

Answer:

x=23

Step-by-step explanation:

Hello There!

Remember the exterior angle of a triangle is equal to the opposite interior angles of a triangle

137-x=2x+3x-1

now we can solve for x

step 1 combine like terms

2x+3x=5x

now we have

137-x=5x-1

step 2 add 1 to each side

-1+1 cancels out

137+1=138

138-x=5x

step 2 add x to each side

-x+x cancels out

5x+x=6x

now we have

138=6x

step 3 divide each side by 6

6x/6=x

138/6=23

we´re left with x=23
