Answer:

Olga's mistake was in Step 3 because she divided the entire equation by 3 instead of dividing it by 1/3.

Answer:

Step-by-step explanation:

These are logically difficult,  so it makes sense to me you're asking about this.

so  A = 1/2 (big arc - small arc)

and 360 = big arc + small arc

then

360 - small arc = big arc

so rewrite  the top equation

A = 1/2(360-small arc -small arc)

63 =  1/2( 360 - 2 small arc)

2* 63 = 360 - 2 small arc

126 = 360 - 2 small arc

2 small arc = 360-126

2small arc = 234

small arc = 234/2

small arc = 117

x = 117°

How to find the missing side of a triangle while only given angles and one side?
OLga [1]
Hi there!

Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)

Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!

Simplify (7x^2-4x+2)-(x^2 +4x-6)
tamaranim1 [39]
(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)
