1: b=9
2: a= 24
3: c=17
4: b=10
Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10
Answer:

Step-by-step explanation:
x and 52 are supplementary, so they add up to 180°

Answer:2w + 20
Step-by-step explanation:
See, the carpet has a rectangular measure of 10 feet.
It's width is 'w'
We, know that perimeter is the sum of all sides.
Now there are two equal sides which we consider length and two other equal sides for width.
So, we have to add all sides which gives 20 +2w
Also general formula for perimeter is 2(length + breadth)
So, our ans. is 2w + 20
Hope it helps!!!
