If sin (x-3)° = cos (2x + 6)°, then what is the value of x?

Travka [436]

Answer:

if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.

----------

Note: sin and cos are complementary functions....

sin(x) = cos (90-x)

-------------------

Your Problem:

sin(x-3) = cos(90-(x-3))

Equation:

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29

URGENT WILL MARK BRAINLIEST <br>Show your work and solve for x and y.<br>3x + y = 8<br>2x + 4y = 12

mars1129 [50]

3x+y=8--(1)

2x+4y=12

x+2y=6--(2)

(1)×1 and (2)×3

$\\ \rm\Rrightarrow 3x+y=8$

$\\ \rm\Rrightarrow 3x+6y=18$

Subtract both

$\\ \rm\Rrightarrow -5y=-10$

$\\ \rm\Rrightarrow y=\dfrac{-10}{-5}$

$\\ \rm\Rrightarrow y=2$

Put the value in eq(2)

$\\ \rm\Rrightarrow x+2(2)=6$

$\\ \rm\Rrightarrow x+4=6$

$\\ \rm\Rrightarrow x=6-4=2$
