Solve for X in the given interval. sec x = -2sr3/3, for pi/2 less than or equal to x less than or equal to pi

B

Step-by-step explanation:

Using the trig. identity

cos x =

Given

secx = - , then

cos x = - × = - = - , thus

x = (- ) = → B

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
