I hope this helps but it is either d or a because parentheses and another term for multiplication and so is a dot
At the first question is t=3
Second is -54
Third x=-3
Forth -36
Answer:
X as an angle will be equal to 140°
Step-by-step explanation:
As AO = BO, AOB is an Isosceles triangle which has 2 equal angles OAB=OBA=20°, therefore BOA is equal to 140°
x is the angle opposite to BOA which will have the same angle measure.
The answer is 36°
Hope that helps, Good luck! (:
