Answer:
Third angle = 70 degrees
tan (70) = 10 / x
x = 10 / tan (70)
x = 10 / 2.7475
x = 3.6396724295
x = 3.6 cm (rounded)
Step-by-step explanation:
The answer is 71°.
x = angle
3x = 90 - x - 14
4x - 76
x = 19°
90 - x = 71°
The surface of a sphere is given by the formula:
area=4πr²
Data:
r=30 m
area=4ππ(30 m)²=3600π m².
Answer: the area of this sphere is 3600π m².

Answer:
<em>Equation of the parabola x² = -12.56 y</em>
Step-by-step explanation:
<u>Explanation</u>:-
<em>Given Y- intercept ( 0, -3.14)</em>
<em>Given Focus is ( 0 , -a) = ( 0, -3.14)</em>
<em>So a = 3.14 center C(0,0)</em>
<em>The graph of the parabola is downwards and the axis of the parabola is Y-axis.</em>
<em>Equation of the standard parabola x² = -4 a y</em>
<em> x² = -4 (3.14) y</em>
<em> x² = - 12.56 y</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>Equation of the parabola x² = -12.56 y</em>
