Your answer would be a) 60 - x°. This is because angles in a triangle add up to 180°, and as angle B is 90 and angle C is x + 30, that means angle A must be 180 - (90 + 30 + x) which is 180 - (120 + x), which when simplified equals 60 - x. I hope this helps!
The answer is 15/8, hope this helps
Answer:
5.5
Step-by-step explanation:
2 times 3 is 6 then but to the other side so plus 6 then You have 2y=11
then you dived it by two so 11 dived by 2 and you get 5.5
225 (since the fraction is over 180° (because 5Π/4 > Π we know that the answer must be bigger than 180° (because 180° = Π (radians)
and its less than 270° because 270° = 3Π/2 or 6π/4
