Find x in this right triangle

Answers

Since the triangle is right angled, we may use pythagoras theorem to find the third side.

Pythagoras theorem :-

KI^2 + JI^2 = KJ^2

substituting the known values in the formula,

x^2 + 3^2 = 5^2

x^2 + 9 = 25

x^2 = 25 - 9

x^2 = 16

x = √16

x = 4

How many times longer is one centimeter than one millimeter

Answers

A kilogram is 1,000 times larger than one gram (so 1 kilogram = 1,000 grams). A centimeter is 100 times smaller than one meter (so 1 meter = 100 centimeters). A dekaliter is 10 times larger than one liter (so 1 dekaliter = 10 liters).

Solve for x
√(x - 2)  = 0

Answers

To solve for x, you need to isolate/get x by itself in the equation:

√(x-2) =0       Square ² both sides to get rid of the square root √

(√(x-2) )^2=(0)^2

x - 2 = 0           Add 2 on both sides

x - 2 + 2 = 0 + 2

x = 2
