Answer:
Step-by-step explanation:
6) taking 45 degrees as the reference angle,
the adjacent side is √6
The opposite side is x
The hypotenuse is y
Therefore, we would apply trigonometric ratio.
Tan # = opposite side / adjacent side
Tan 45 = x/√6
1 = x/√6
x = 1 × √6 = √6
Cos # = adjacent side/hypotenuse
Cos 45 = √6/y
Cos 45 expressed in surd form is √2/2. Therefore,
√2/2 = √6/y
y √2 = 2√6
y = (2√6)/√2
On enlarging the rectangle, the proportion or ratio of Length to Height will stay the same.
The ratio of original length to height is 13 : 6
The ratio in enlarged rectangle will stay the same. Let the height of enlarged rectangle is y cm. So we can write:

Therefore, the height in enlarged rectangle will be 9 cm
The answer is B.103 degrees
No 8-12 is like 3:4 and 3-6 is like 1:2
