If tanx =√24 and cosx =−2√23, find sinx.
mylen [45]

Answer:

Step-by-step explanation:

sin(x)=cos(x) × tan(x)

=(-2√23)×(√24)

=(-2√23)×(2√6)

=(-4√138)

=(-4(2√(3×23)))

=(-8√69)

Try #5/#6 and #7 and if you have a chance can u try to do 8,9,10,11,12&13 it’s ok if u can’t do those just try 5,6,7
Natalija [7]
8. Adjacent and complementary angles are #1 & 2, since they are next to each other and added together equal 90°
9. Vertical angles are # 1 & 4, since they are opposite to each other.
10. Adjacent and supplementary angles are #4&5, since they are next to each other and add up to 180°
11. The acute angles are #1&2&4, since they are all less than 90°
12. The obtuse angles are #5&6, since they are greater than 90°
13. The angle measurements are:
1: 42°
2: 90-#1 = 90-42 = 48°
3: right angle = 90°
4: opposite #1 = 42°
5: 180-#4 = 180-42 = 138°
6. opposite #5 = 138°


btw, we cannot see the diagram for #5,6,7

Find the circumference with the given radius.round to the nerest tenth.use 3.14 π r = 7cm​
brilliants [131]

Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

C=2\pi r

So we can substitute 7 for r and 3.14 for pi:

C=2(3.14)(7)=43.96 cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length
lisov135 [29]

Answer:

B. 4\sqrt{7}

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

h = \sqrt{(xy)}

Where,

h = the length of the altitude,

x and y are the lengths of the 2 segments formed.

Therefore, the length of the altitude = h = \sqrt{(14*8)}

h = \sqrt{112}

h = \sqrt{16}*\sqrt{7}

h = 4\sqrt{7}
