Answer:
65°
Step-by-step explanation:
<u>Properties of a triangle:</u>
- Triangles always have 3 sides
- <u><em>The sum of the interior angles of a triangle must be equal to 180°.</em></u>
<u>To solve:</u>
- <u>Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:</u>
- <em>a</em> + <em>b</em> +<em> c</em> = 180
- (The variables can be assigned to any value in this situation)
- <u>Since two angles are already given, replace 2 variables:</u>
- <em>a</em> + 85 + 30 = 180
- <u>Solve the equation by subtracting on both sides:</u>
- <em>a</em> = 65
- The value of <em>a</em> is the measure of the missing angle. The problem is solved.
Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
<em> 180</em>
<em>- 85</em>
<em>----------</em>
<em> 95</em>
subtract the remaining angle
<em> 95</em>
<em>- 30</em>
<em>---------</em>
<em> 65</em>

The equation of the ellipse ( in the standard form ) :
x² / a² + y²/ b² = 1
a = 6, b = 5 ( from a graph )
Answer: D ) x² / 36 + y² / 25 = 1
8 and -7. 8 + (-7) = 1 and 8 times -7 = -56
