The value of the sine, cosine and tangent of the figure will be found as follows:
a] Sine
sin x=(opposite)/(hypotenuse)
opposite=7
hypotenuse=25
thus:
sin x= 7/25
b] Cosine
cos x=adjacent/hypotensue
adjacent=24
hypotenuse=25
cos x=24/25
Tangent
Tan x=opposite/adajcent
opposite=7
adjacent=24
thus
tan x=7/24
Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Answer:JKL
Step-by-step explanation:A 270 degree rotation represents three 90 degree rotations
Rotating ABC by 90 degrees three times places it in the position of JKL
So, the answer is B. JKL

Answer:
- 20c +110m = 340; c + m = 8
Step-by-step explanation:
Let c and m represent the number of commercials and movies playing Alexa's songs, respectively.
20c +110m = 340 . . . . . total royalties earned
c + m = 8 . . . . . . . . . . . . total number of plays
___
Alexa's songs were played in 6 commercials and 2 movies.
