Solve the equation cos2x = -1\2, for 0 < x < 360°.

natta225 [31]

Answer:

x = 60°, 120°

Step-by-step explanation:

If we let $t=2x$ , our equation now becomes $\cos{t}=-1/2$ , which is true for two values of t: 120° and 240°. Since t = 2x, we can say that $120^{\circ}=2x$ and $240^{\circ}=2x$ , and therefore $x = 60^{\circ}$ and $x=120^{\circ}$

Find the measure of the missing sides in each special right triangle. Simplest radical form

lapo4ka [179]

Answer:

X= $8\sqrt{2}$ Y= $7\sqrt{2}$

Step-by-step explanation:

The first one is 45-45-90 right angled isosceles triangle.

The length of the hypotenuse ie.X can be found with the help of Pythagoras Theorem.

$a^{2} + b^{2} = X^{2}$

where a and b are the remaining sides of the triangle,

$8^{2} +8^{2} =X^{2} \\2*8^{2} =X^{2}\\X=8\sqrt{2}$

X= $8\sqrt{2}$

In the second triangle we have to apply trigonometry,

cos θ= $\frac{Length OfAdjacentSide}{LengthOfHypotenuse}$

cos 30°= $\frac{\sqrt{3} }{2}$

$\frac{\sqrt{3} }{2}$ = $\frac{Y}{14}$

Thus, Y= $7\sqrt{2}$ inches

Answer:

the answer would be x=6

to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent

hope this helps :)
