Find two angles that satisfy each equation.
9. sin(4x +30)° = cos(-2x + 54)"

11. cos(5x + 49) = sin(3x + 57)

13. sin(2x + 30)° = cos(3x + 5)

15. cos(3x - 10) = sin(3x - 20°

10. sin(-2x +92)° = cos(x+8)°

12. cos( - 3x + 106)° = sin(7x - 64)

14.
sin(5x - 12) = cos(x + 54)

16. cos(7x - 68)° = sin(-3x + 110)

right

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
