Okay so because of the due to the rule that the hypotenuse is always the longest side on right angles so with the Pythagorean theorem we can infer that

a^2+b^2=c^2

19) 9.3^2+b^2=13.2^2
86.49+b^2=174.24
b^2=87.75
B=9.367

20) 2^2+b^2=7^2
b^2=45
b=6.708

21) 5^2+4^2=c^2
c^2=41
b=6.403

22) 15^2+15^2=c^2
c^2=450
c=21.213

23) 10^2+b^2=12^2
b^2=44
b=6.633

24) 6^2+b^2=9^2
b^2=45
b=6.708

Answer

x = 18 cm

Step-by-step explanation:

Here, we want to calculate the value of x

let half of x = b

so b is the base of each right-triangle

As we can see, the triangle is isosceles

we can calculate the length of the base of one of the smaller right angled triangle and multiply by 2 to get the full x length

According to Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides

15^2 = 12^2 + b^2

225 = 144 + b^2

b^2 = 225-144

b^2 = 81

b = √81

b = 9

but x = 2b

x = 2(9)

x = 18 cm

svetoff [14.1K]

Answer:

If 23-26, that is -3

Well, because 23 can't minus 26, that's why you have to rearrange so that you can find the correct answer by letting -26 + 23.
