1 answer:

5 0

Apply the law of cosines. and solve for A

$14^{2} = 11^{2} + 11^{2} - 2(11)(11)cos(A) \\ 
196 = 121 + 121 - 242cos(A) \\ 
-46 = -242cos(A) \\cos(A) = 0.1900826446$

A = 79.04239272, or 79

Which of the following triangles are impossible to draw? Choose all that apply.

ioda

I would say a triangle with two right angles because a triangle's angles add to 180 degrees. If a triangle has two right angles, it means that two angles will be 90 degrees, which add to 180 degrees. A triangle must have three angles and sides, and it is not possible for the last angle to be 0 degrees.

Hope this helps

Find the missing angle measure A=51°, B=82°, C=5x+2

Shalnov [3]

I'm assuming you mean triangle angles?
If so, all angles add up to 180 so combine them and set them equal to 180.
51+82+5x+2=180
135+5x=180
5x=45
x=9

I think it would be 72+4x=400
400-72= 328
328/4= 82
So the answer would be 82=x
