Question

please helpppp!!! it’s timed!!!! thank u for helping!!!!!

Answer 1

A

Explanation:

Because the angles must add to 180 we can see the misssing angle is 69

This means that answer is either A or C

Using SOH we can solve for side CD

sin(21)=x/18

18sin(21)=x

x=6.45

If CD= 6.45 this means that the answer is A
