x = 109
Step-by-step explanation:
1. All of a triangles angles will add up to 180 degrees
2. Take 180 then subtract 48 from 180
3. Your new number is now 132. Take 132 then subtract 23.
4. Answer is 109
Answer:
y = 1/2x - 1
Step-by-step explanation:
When you put all three equations from the question into a graph and then input the equation i just gave you it will be perpendicular to line B & C, also it will be parallel to line A. Finally you can check yourself that it also has a y-intercept of (0,-1) & an x-intercept of (2,0). Hopefully this helps out & gets brainliest. xD
X² + 10x + 25 = 16
x² + 10x + 25 - 16 = 0
x² + 10x + 9 = 0
(x + 1)(x + 9) = 0
x(x+9) + 1(x+9) = 0
x² + 9x + x + 9 = 0
x² + 10x + 9 = 0
(x + 1) = 0
x = -1
(x + 9) = 0
x = -9
