The value of x is ____
ruslelena [56]
Answer: x = 96

---------------------------------------

Work Shown:

The sum of the exterior angles for any polygon is 360 degrees. So add up the three exterior angles, set the sum equal to 360 and solve for x

130+134+x = 360
264+x = 360
x+264 = 360
x+264-264 = 360-264
x = 96

As a check,
130+134+x = 130+134+96 = 360
so the answer checks out

Find the missing side lengths. Leave your answers as radicals in simplest form.
steposvetlana [31]

The length of missing sides x = 5 units and y = 5 units.

<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>

In ΔABC,

AB (Base) = y  ,      BC(Hypotenuse) = 5\sqrt{2}   ,       CA (perpendicular) = x

and ∠ABC = 45^0

Now,

tan 45^0  = perp. / base

1 = x /y

x= y .................(i)

again,

sin 45^0 = perp. / Hypo.

\frac{1}{\sqrt{2} } = \frac{x}{5\sqrt{2} }

x = 5

put in equation (i), we get

y = 5

Thus, the length of missing side of the given triangle is x = 5 units and y =  5 units.
