We can solve this problem using the Pythagorean Theorem. The Pythagorean Theorem states, that with hypotenuse c, and legs a and b, a² +b² = c², and since this is a right triangle, that principle is true here. In this problem, we have the length of the hypotenuse and leg a. So, we can insert the values of the variables and then simplify to find out the length of b. 15²+b²=20²b²=400-225b²=175b=√175
Answer:
Only B
Step-by-step explanation:
so option B is correct
Answer:
x = 3
Step-by-step explanation:
The triangles are similar.
x + 9 is twice 2x.
x + 9 = 2(2x)
x + 9 = 4x
9 = 3x
x = 3
Hello! :)
Answer:
Solve for x:
Begin isolating the variable by adding "c" to both sides:
Divide both sides by a/b, or multiply by the reciprocal (b/a)
Therefore:
Answer:
200 soldiers stand in a straight row.
Beginning from the left, the soldiers call out: 1, 2, 3, 4, 5, 1, 2, 3, 4, 5,
1, 2, 3, 4, 5,
Following that, the soldiers call out from the right: 1, 2, 3, 4, 1, 2,
3, 4, 1, 2, 3, 4,
How many soldiers call out the same number?
