Answer:

- 8\frac{ 1}{ 2}

Step-by-step explanation:

- 4x + 8 = 42 \\  - 4x = 42 - 8 \\  - 4x =   34 \\ x =  \frac{ 34}{ - 4}  \\ x =  - \frac{ 17}{ 2}  \\ x =  - 8\frac{ 1}{ 2}  \: or \: x = - 8.5

What are the three angle measures in the triangle shown below
sergeinik [125]
B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B
