Find the value of the angle θ rounded to 1 DP.

ok first we add 9 and 29 together

38

now we add 90

128

so the other angle is

52

so we just use the formulas

and

Side a = 26.56371

Side b = 43.14662

Side c = 34

so the side with a x on it is 26.6

so know we have to do the same thing but not including the top part

ok so the side with x on it is 18.8

so 26.6-18.8=7.8

x=7.8

*WARNING* This shoud be close to the answer but may to up to a couple dp higher or lower sorry i just don't have time to be more accurate

Hope This Helps!!!
