Okay!
10% of 55 is 5.5
(Butterfly method)
10/100 = n/55
10*55= 550
550/100= 5.50

30% of 900 is 270
30/100 = n/900
30*900 = 27000
27000/100 = 270

25% of 200 is 50
25/100 = n/200
25*200 = 5000
5000/100 = 50

20*4-30
80-30
50

(2*7)+12
14+ 12

Find the value of x in the isosceles triangle shown below.
Reptile [31]

Answer:

x=10

Step-by-step explanation:

We can use the Pythagorean theorem to find x

The height meets the base at a right angle

The base is bisected ( cut in half) so the base is 6 the height is 8

a^2 + b^2 = c^2

6^2 + 8^2 = x^2

36+64 = x^2

100 = x^2

Taking the square root of each side

sqrt(100) = sqrt(x^2)

10 = x
