Answer:
a = 5.3
Step-by-step explanation:
Plug the length of the other two sides into the Pythagorean Theorem and solve.
a² + b² = c²
a² + 6² = 8²
a² + 36 = 64
a² = 28
a = √28
a = 5.291502622 ⇒ 5.3 (to the nearest tenth)
The length of "a" is 5.3.
Hope that helps.

Answer:
11.2 mm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert Values:
x² + 3.8² = 11.8²
x² + 14.44 = 139.24
x² = 139.24 - 14.44 (subtract)
x² = 124.8
x = √124.8 (square root)
x = 11.1714 ≈ 11.2 (rounded to 3 significant figures)
Answer:
0 = -54
Step-by-step explanation:
4(3x + 8) − 9 = 2(6x − 8) − 15
12x + 32 - 9 = 12x - 16 - 15
12x + 23 = 12x - 31
12x = 12x - 54
0 = -54
No solutions.
Best of Luck!
