Answer:
Step-by-step explanation:
1. 10² + 7² = x²
149 = x²
x = √149
2. x² + 19² = 21²
x² = 21² - 19² = 80
x = √80 = 4√5
3. x² + 16² = 27²
x² = 27² - 16² = 473
x = √473
4. 5.3² + 12.8² = x²
191.93 = x²
x = √191.93
5. 9² + 20² = x²
481 = x²
x = √481
6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2
x = 31 - 12√2
26 cm
we can make an equation to find the lengths
2(x+7x-2) = 60
x : length of width
7x-2 : the length of length
2 : the two pairs of length and width
solving this equation, we get x = 4
but that is not the answer
we have to plug in x=4 into 7x-2
7*4-2 = 28-2 = 26
let's say that point is point C, thus
