I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
2x4 is the answer to 4x-2=38
Answer:
-12
Step-by-step explanation:
-12/2 = -6
-6+15 = 9
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
