To find a, you use a formula called the law of cosines:

The law of cosines tells us:

a^2 = b^2 + c^2 - 2bc cosA

So lets plug in the values:

a^2 = 4^2 + 3^2 -2(4)(3)cos(32)

a^2 = 25-24cos32

a^2 is roughly equal to 4.97

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Let the first number = x

Let the second number = x + 9

Let the third number = 4x

Together they make 123

x + x + 9 + 4x = 123 combine the left

6x + 9 = 123 Subtract 9 from both sides

6x = 123 - 9

6x = 114 Divide by 6

x = 114/6

x = 19

=================

First number = 19

Second number = 19 + 9 = 28

Third number = 4*19 = 76
