Answer:

Step-by-step explanation:

$d-10-2d+7=8+d-10-3d\qquad\text{combine like terms}\\\\(d-2d)+(-10+7)=(d-3d)+(8-10)\\\\-d-3=-2d-2\qquad\text{add 3 to both sides}\\\\-d=-2d+1\qquad\text{add}\ 2d\ \text{to both sides}\\\\d=1$

Find θ, 0° ≤ θ < 360°, given the following information.

ludmilkaskok [199]

Answer:

210°

Step-by-step explanation:

Given

sinΘ = - $\frac{1}{2}$

Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is

Θ = $sin^{-1}$ ( $\frac{1}{2}$ ) = 30° ← related acute angle

Thus the required angle in the third quadrant is

Θ = 180° + 30° = 210°
