The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
Answer:
The first five terms in Pattern A are 5, 11, 17, 23, and 29
Step-by-step explanation:
Pattern A:
5 + 6a
Pattern B:
5 + 3a
Take a = 1 and compare ;
Pattern A:
5 + 6(1) = 11
Pattern B:
5 + 3(1) = 8
A ≠ 2B
B ≠ 1/3A
First 5 terms in pattern A :
Pattern A:
5
5 + 6(1) = 11
5 + 6(2)= 17
5 + 6(3) = 23
5 + 6(4) = 29
5 + 6(5) = 35
Pattern B cannot have a term 0 as it starts from 5
A

Seven halves would equal to 3.5 wholes. What you do is divide 7 by 2 to find out how many wholes their are.
Year 1: 2,000 x 3% = 60 2,000 + 60 = 2,060 Year 2: 2,060 x 3% = 61.8 2,060 + 61.8 = 2,121.8 So, the answer is there will be £2,121 in the bank account after 2 years.
