Answer:

it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)

HELP!!! WILL GIVE BRAINLIEST +LIKE AND 5 STARS ANSWER THE QUESTION IN THE PICTURE
Sergeu [11.5K]

Answer:

13) B

14) A

Step-by-step explanation:

13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:

sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4

To solve for side a, use cosine:

cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1

14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):

cos 38° = b/16 ---> b = 16cos38 = 12.6

To find side a, use sine:

sin 38° = a/16 ---> a = 16sin38 = 9.9
