Answer is choice A) 20/21
The first step is to use the pythagorean theorem a^2+b^2 = c^2 to find the missing side to be 21. Once you know this, you find the ratio of the opposite and adajcent sides. The opposite side is the leg furthest from the angle x (the side labeled 20). The adjacent side is the leg closest to or touching the angle x (the side labeled 21 which was found earlier).
So, tan(x) = opposite/adjacent = 20/21
Answer:
centre = (4, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 4)² + y² = 25 ← is in standard form
with (h, k) = (4, 0) and r = = 5
Thus centre = (4, 0) and radius = 5
Answer:
i think its 84...
Step-by-step explanation:
not to sure
Answer:
maybe it is -5
Step-by-step explanation:
(1,6) (3,-4)
i did a little math and minused -4 by 6 and divided that by 3-1 to get -5 which is a formula too i think?
Answer:
If C is a supplementary angle (Adds to B to equal 180 degrees), then C=180-67=113 degrees.
If C is a complementary angle (Adds to B to equal 90 degrees), then C=90-67=23 degrees.
