Answer:
2x
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = 
· · 
This can be simplified to be 2x
Answer:
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.

Answer:
28 : 14
Step-by-step explanation:
4 : 2
4 + 2 = 6
42 ÷ 6 = 7
7 × 4 = 28
7 × 2 = 14
Answer:
Step-by-step explanation:
It is assumed PQS and RQS are similar triangles.
<u>The ratio of corresponding sides is equal:</u>
<u>Substitute side lengths and solve for x:</u>
- 15/(3x - 4) = 21/(5x - 16)
- 15(5x - 16) = 21(3x - 4)
- 5(5x - 16) = 7(3x - 4)
- 25x - 80 = 21x - 28
- 25x - 21x = 80 - 28
- 4x = 52
- x = 52/4
- x = 13
