Answer:
a = 95
Step-by-step explanation:
a+ 35+ 50 = 180
Combine like terms
a+ 85 = 180
Subtract 85 from each side
a+85-85 = 180-85
a = 95
The new perimeter after a dilation with a scale factor 3/4 is 21 units
<h3>What is perimeter?</h3>
The perimeter of a shape is the sum of its side lengths
The perimeter of the shape is given as:
The scale factor is given as:
The perimeter after the shape is dilated is calculated using:
So, we have:
Hence, the new perimeter is 21 units

Answer:
5.477
Step-by-step explanation:
Here we have to get the value √ ( x²+y² ) in this question where the values of x² and y² are given to be 20 and 10 respectively.
Let A = √ ( x²+y² ) =√(20+10) {Since the value of x² =20 and that of y² =10}
⇒ A= √30 =5.477
Therefore, the value of √ ( x²+y² ) is 5.477. (Answer)
