To find out the missing leg of a right triangle, you have to use the Pythagorean Theorem which is a^2 + b^2 = c^2. C is the hypotenuse. So, substitute the numbers into that equation.
2^2 + 4^2 = x
4 + 16 = x
20 =
Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430
