My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)
It is an isosceles triangle which means that side BD=BC, The angles will be also equal i.e. Angle B= Angle C
<h3>Now,</h3>
- Angle B = 4x+19
- Angle C = 2x+33





<h3>Calculating the angles:</h3>


Now, We will find ∠D with the help of angle sum property of triangle

<em>The measure of angles are; 47°,47°,86° respectively</em><em>.</em><em>.</em><em>.</em>
Answer: B)° -270° and 90°
<u>Step-by-step explanation:</u>
Ray 1 is located on the x-axis in Quadrant 1 → 0°
Ray 2 is located on the y-axis in Quadrant 1 → 90° = -270°
The difference between the two angles is:
- 90° - 0° = 90°
- -270° - 0° = -270°
