Answer:
B. 43°
Step-by-step explanation:
Internal angles of the triangle are:
So It is a right triangle and the missing angle is:
The answer is B) 43°
180° - 133° = 47° (that's one of the angles inside the triangle)
180° - 90° = 90° (the other angle)
Every angle inside a triangle added equals 180°, therefor:
180° - (47° + 90°) = 43°
How much is the ouside of the box?
the answer is c i know it is
6
3 sqrt(20) / sqrt(5)
We know that sqrt(a) /sqrt(b) = sqrt(a/b)
3 sqrt(20/5)
3 sqrt(4)
3 *2
