Wednesday Problem (Triangle Angle Calculation)

Step1: Define unknown angles

Let each equal angle be $x$.

Step2: Set up angle sum equation

$70^\circ + x + x = 180^\circ$

Step3: Simplify and solve for $x$

$70^\circ + 2x = 180^\circ$
$2x = 180^\circ - 70^\circ = 110^\circ$
$x = \frac{110^\circ}{2} = 55^\circ$

Step1: Add negative integers

$-3 + (-9) = -3 -9 = -12$

Step2: Subtract negative integer

$-5 - (-2) = -5 + 2 = -3$

Step3: Multiply negative integers

$(-3)(-6) = 18$

Step4: Divide negative integers

$-27 \div 3 = -9$

To plot each point:

1. For point A $(4, -3)$: Move 4 units right along the x-axis, then 3 units down along the y-axis and mark the point.
2. For point B $(-2, 1)$: Move 2 units left along the x-axis, then 1 unit up along the y-axis and mark the point.
3. For point C $(0, 2)$: Stay at the origin (x=0), move 2 units up along the y-axis and mark the point.

Answer:

$55^\circ$
