3 0
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 = \pi/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7\pi/6
360-3=330 = 11\pi/6

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180°

6p + 6p + 3 p = 180

15p = 180

p = 180/15

p = 12

Angles are:

6p = 6*12 = 72°

3p = 3*12 = 36°

Angles are: 72°, 72° , 36°

HELPPP THIS IS DUE SOON! I WILL MARK BRAINLIEST
expeople1 [14]

Answer:

7.3

Step-by-step explanation:

For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.

Distance = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

X2 is 7 (X coordinate of school)

X1 is 5 (X coordinate of friend's house)

7 - 5 = 2

2^2 = 4

Y2 is 7 (Y coordinate of school)

Y1 is 0 (Y coordinate of friend's house)

7 - 0 = 7

7^2 = 49

4 + 49 = 53

\sqrt{53} = 7.2801...

<em>Round to the nearest tenth...</em>

<em>7.3</em>
