91 divided by 7 is 13. so he can paint 13 in 1 week. 13 x 4 equals 52 so he can paint 52 portraits in 4 weeks.
In the triangle , Angle A is 51.1 degrees, B is 54.5 degrees , C is 74.4 degrees.
<h3>What is a Triangle ?</h3>
A triangle is defined as a polygon with three sides , three angles and three vertices.
Using the Law of Cosine to solve the Triangle and to determine the value of all the angles
c² = a²+ b² -2abCosC
a = 42 , b=44 , c = 52
52² = 42² + 44² -2 * 42 * 44 cos C
2704 = 1764 + 1936 -3696 cos C
cos C = 0.269
C =74.4 ° (degrees)
Similarly calculating for A and B will give
Angle A is 51.1 degrees
Angle B is 54.5 degrees
