Solve the right triangle.
A = 48.31º. c = 49.9

Assuming angle A is opposite to side a, B is the opposite to side b, and angle C is the opposite to side c.

The right triangle has the following angles:

A = 48.31º, B = 41.69º and C = 90º.

The sides are:

, and c = 49.9.

Step-by-step explanation:

The inner sum of a triangle = 180º.

A=48.31º,

C=90º

A + B + C = 180º

48.31º+ B + 90º = 180º

B = 180º - 90º - 48.31º

B = 41.69º

We can apply the Law of Sines to solve for unknown sides:

We know that sin(90º) = 1.

Then, a is:

Thus, b is:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
