A triangle has sides of length 3 cm, 5 cm, and 7 cm.
BlackZzzverrR [31]

Answer:

C=120 degrees

Step-by-step explanation:

We can use the law of cosines to find an angle when we have all three sides

(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)

49 = 25 +9 -30Cos(c)

49= 34 -30Cos(c)

15 = -30Cos(c)

Cos(c) = -1/2

C=120 degrees

What appears to be the solution to the system of equations shown in the graph below?
AlladinOne [14]

Given:

The system of equation is,

3x-4y = -2 -------- (1)

-6x+5y = 7 -------- (2)

To find the solution.

To solve the system of equation,

From (1) we get, 3x = -2+4y

Putting this value into (2) we get,

-6x+5y = 7

or, -2(3x)+5y = 7

or, -2(4y-2)+5y = 7

or, -8y+4+5y = 7

or, -3y = 7-4

or, -3y = 3

or, y = -1

From (1) we get,

3x = -2+4(-1)

or, 3x = -6

or, x = -2

Hence,

The solution is x= -2 and y = -1
