Sin =9/15 . Find tan 0

Mathematics
1 answer:
ELEN [110]3 years ago
3 0

Answer:

c. 9/12

Step by step explanation.

Given: sin = 9/15

and,

sin =  \frac{opp.}{hyp.}

tan =  \frac{opp.}{adj.}

thus, find adj. side

by using Pythagoras theorem

{c }^{2} =   {a}^{2}  +  {b}^{2}

then,

let adj. side be a^

{a}^{2}  =  {c}^{2}  -  {b }^{2} \\  {a}^{2}   =  {15 }^{2}  -  {9}^{2}  \\  {a}^{2}  = 144 \\ a = 12

thus,

adj. side is 12

then,

tan of the angle = 9/12

Select all expressions that represent a correct solution to the equation 6(x+4)=20
Sergeeva-Olga [200]

Answer:

D. 20 ÷ 6 − 4

E. 1/6(20 − 24)

F. (20−24) ÷ 6

Step-by-step explanation:

6(x + 4) = 20

6(x) + 6(4) = 20

6x + 24 = 20

     - 24  - 24

6x = -4

/6    /6

x = -4/6 or x = -2/3

D. 20 ÷ 6 − 4

20/6 - 4

20/6 - 24/6

-4/6 = -2/3

E. 1/6(20 − 24)

1/6(-4)

-4/6 = -2/3

F. (20 − 24) ÷ 6

- 4 / 6

-4/6 = -2/3

Hope this helps!

What is the length of the arc on a circle with radius 21 in intercepted by a 25° angle? Round your answer to the nearest tenth.
Lana71 [14]

Answer:

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ is the central angle formed at the center of the circle.

r represents the radius of the circle.

π represents a constant whose value is 3.14

From the information given,

r = 21 inches

θ = 25 degrees

Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
