The answer is 41.41
Since we know the side that is opposite to a, and the hypotenuse, we have enough information to get the cosine of a. The cosine is 45/60. If we know the cosine of an angle, we can get the arccos of that value to get the angle. The arccos of 45/60 is about 41.41.

Answer:

(y - 3 )² = 8 ( x - 4 )

The given vertex of Parabola is ( 4 , 3)

And Directrix is X = 6

The equation of parabola is

( y - k )² = - 4 ( P) ( x - h )

Now p = 4 - x = 4 - 6 = - 2

And given value of ( k , h) = ( 4 , 3)

Or ( y - 3 )² = - 4 ( - 2) ( x - 4 )

Or, ( y - 3 )² = 8 ( x - 4 )

Hence The equation of parabola with directrix x = 6 And

vertex ( 4 , 3 ) is ( y - 3 )² = 8 ( x - 4 ) Answer

Answer:

95°
85°

Step-by-step explanation:

<u>Given angles are consecutive interior angles which sum up to 180°</u>

9x + 14 + 8x + 13 = 180
17x = 180 - 27
17x = 153
x = 153/17
x = 9

<u>Angles</u>

9x + 14 = 9*9 + 14 = 81 + 14 = 95°
8x + 13 = 85°
