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

Susan enlarged a rectangle with a height of 6 cm and length of 13 cm on her computer. The length of the new rectangle is 19.5 cm
amid [387]
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:

13:6=19.5:x \\  \\ 
 \frac{13}{6} = \frac{19.5}{x} \\  \\ 
x=19.5* \frac{6}{13}=9

Therefore, the height in enlarged rectangle will be 9 cm
