118 + 23 = 141
180 = Triangle
180 - 141 = 39
39 is the answer
Answer:
B
Step-by-step explanation:
Okay! So before we do this, first we have to understand the function. The function is,
y = ax^2 + bx + c, where a does not equal to 0.
The answer is not A, since bx is bx^2 which is incorrect.
The answer isn't C, since there isn't an ax^2 or a bc.
The answer isn't D since there a can't be 0.
The only correct answer is B, for it has all the parts.
x^2 + 2x -5.
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
