Consider a triangle ABC like the one below. Suppose that a = 42, b=44, and c= 52. (The figure is not drawn to scale.) Solve the
maksim [4K]

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

The sides of two triangles are 6, 9, 12 inches and 2.5, 3.75, and 5 inches respectively. Are the triangles similar ? Explain you
AfilCa [17]

Answer:

Since, the sides are proportional. Therefore, the two triangles are similar.

Step-by-step explanation:

Since:

\frac{6}{2.5}  = \frac{60}{25}  \\                    = \frac{12}{5}

and

\frac{9}{3.75}  = \frac{900}{375}  \\                    = \frac{180}{75} \\                    = \frac{36}{15} \\                    = \frac{12}{5}

also,

\frac{12}{5}  = \frac{12}{5}

i.e., The sides are proportional.

Therefore, the two triangles are similar.
