Solve the equation sin theta = .3 to the nearest tenth. Use the restrictions 90 < theta <180

1 answer:

5 0

Sinα=3/10

α=arcsin(3/10)°

α≈17.5°

But since we are restricted to 90°<α<180° the angle must lie in the second quadrant so:

α≈(180-17.5)°

α≈162.5°

Answer:

x = 7

Step-by-step explanation:

Expand 3x+2(x-5)=25 which looks like

3x+2x-10=25

Add similar elements: ( 3x+2x = 5x)

5x-10=25

Add 10 to both sides

5x-10+10 = 25 + 10

Simplfy

5x = 35

Divide both sides by 5

5x ÷ 5 = 35 ÷ 5

Simplfy:

x = 7

If x=3 what is 3x -5(9x3) divided by 2 and does any one wanna talk and at school?

mart [117]

<h3>Given :- </h3>

$\quad \qquad \bullet \quad \sf x = 3$

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

<h3>Solution :- </h3>

Let's Start :-

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

Putting the respective value of x we have ;

${ : \implies \quad \sf \dfrac{3\cdot 3- 5 (27 )}{2}}$

${ : \implies \quad \sf \dfrac{9- 135}{2}}$

${ : \implies \quad \sf - \dfrac{126}{2}}$

${ : \implies \quad \bf - 61}$

$\quad \qquad { \bigstar { \underline { \boxed { \pmb { \bf { \red { \underbrace { \therefore \dfrac{3x - 5 ( 9 \times 3 )}{2} = - 61}}}}}}}}{\bigstar}$
