Answer:
Scale factor: 4:1
Ratio of perimeter: 4:1
Step-by-step explanation:
So basically, there is difference between the ratio of areas and the scale factor.
The area of a shape is equal to the scale factor squared.
We know that the ratio of the 2 areas is 16:1
So, the scale factor must be: ![\sqrt[2]{16}: \sqrt[2]{1}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%7D%3A%20%5Csqrt%5B2%5D%7B1%7D)
,
Which is basically 4:1
Because the ratio of the scale factor is also equal to the ratio of the perimeter, the ratio of perimeters is also 4:1
Answer:
We know, two angles are said to be complementary, if the sum of their measures is 90
∘
.
Let the angle be x
∘
and its complement is 90
∘
−x
∘
Then, according to the statement,
⇒x
∘
−(90
∘
−x
∘
)=12
∘
⇒x
∘
−90
∘
+x
∘
=12
∘
⇒2x
∘
=12
∘
+90
∘
=102
∘
⇒x
∘
=
2
102
∘
=51
∘
.
Hence, the measure of the angle is x=51
∘
and its complement is 90
o
−x=90
o
−51
o
=39
∘
.
