You add the numbers up so 53
Answer:
∠ 1 = 120°
Step-by-step explanation:
Note that ∠ Q and ∠ R are congruent, that is both 30°, thus
∠ 1 = 180° - (30 + 30)° = 180° - 60° = 120°
The correct answer is 'C'
If X = 2, and Y = 4:
2(2) + 3(4) - 2 - (8 + 1) = 5
4 + 12 - 2 - 9 = 5
16 - 2 - 9 = 5
14 - 9 = 5
= 5
(2) + 3(4) - 9 = 5
2 + 12 - 9 = 5
14 - 9 = 5
= 5
So, your answer would be 'C' X + 3Y - 9
There is no whole number that satisfies the criteria... the only multiples of 15 are 3 and 5 which add to 8 and 1 and 15 which add to 16
