Well first you have to set the two equal to each other
x+40=3x, then subtract x from both sides
40=2x, then divide both by two to get x alone
x=20

They are vertically opposed angles.

They are equal!

So x+40 = 3x and we solve it -> x-3x = -40 -> -2x = -40 -> 2x=40 so x = 20

Verify that [tan(theta) + cot(theta)]^2 = sec^2(theta) + csc^2(theta)
Wittaler [7]

(tanθ + cotθ)² = sec²θ + csc²θ

<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ

<u>Evaluate middle term</u>: 2tanθcotθ = 2*\frac{sin\theta}{cos\theta}*\frac{cos\theta}{sin\theta} = 2

⇒ tan²θ + 2+ cot²θ

= tan²θ + 1 + 1 + cot²θ

<u>Apply trig identity:</u>  tan²θ + 1 = sec²θ

⇒ sec²θ + 1 + cot²θ

<u>Apply trig identity:</u>  1 + cot²θ = csc²θ

⇒ sec²θ + csc²θ

Left side equals Right side so equation is verified

horrorfan [7]
<h3>Answer:</h3>

4, 8, 8

<h3>Step-by-step explanation:</h3>

At each node, three faces meet. One is square (4 sides); the other two are octagons (8 sides). Hence the tiling can be named with three numbers: 4, 8, 8.
