the sum of the measures of the three angles in any triangle is 180 degrees the measure of the smallest angle of the CERN triangl
dmitriy555 [2]
I don't really know how to explain this but I know my answer is correct.

The smallest angle is 16
The medium size angle is 32
The largest angle is 132

If we let S, M, and L be variables, we can make the following equations
S = 1/2 M
M = 2 S
L = 8 S + 4
L + M + S = 180

If you plug in 16 for S, everything falls into place

What is the value of x? Round to the nearest hundredth.
jeyben [28]

Answer:

The correct answer is first option

X = 34.61

Step-by-step explanation:

<u>Points to remember</u>

<u>Trigonometric ratios</u>

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle with base x and hypotenuse = 81.9.

One angle = 65°

To find the value of x

We have Cos θ = Adjacent side/Hypotenuse

Cos 65 = X/81.9

X = 81.9 * Cos 65

 = 81.9 * 0.4226  

 = 34.61

Therefore  X = 34.61

The correct answer is first option
