Answer: 20
Step-by-step explanation:
I suppose the figure that you do not include in your exercise is the one that I attached.
Looking at the figure, it is obvious that the angle COA is divided into two angles of 20 degrees each, so the answer would be 20.
Let one angle be x.
Other angle = x + 30°
Given, angles are complementary;
x + x + 30 = 90
2x = 60
x = 30°
Hence, the angles are 30° and 60°.
Answer:
412^10
Step-by-step explanation:
^^^^^^^^^^^^^^^^^
Answer:
6 because 9 is the length and you only do length times height and 54 divided by 9 is 6 therefore the height is 6
We have that
(x + 3)² = -20(y − 1)
<span>This is actually the vertex form, so we can obtain the vertex already
</span>the vertex is the point (h,k)------------> (-3,1)
4p=-20------------> p=-5
Focus is at (-3,1-5)---------> (-3,-4)
Directrix is at <span>y = 1-(-5)----------> y=6
</span>
the answer is
the directrix is y=6
see the attached figure
