Question

Please help!!!! I need the answers.

Answer 1

Angle A: 40°

Angle B: 50°

Angle C: 90°

Side A: 14

Side B: 12

Side C: 11.2 or 11 if you round to the nearest whole number.

Explanation:

Angle A;

Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.

90-50=40

Angle A= 40°

Side C;

Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.

cos 40°= C/14

C/14= cos 40°

C/14= .8

C= .8 x 14

C= 11.2

Hope this helps! Have a great day! :)
