Answer:
C
Step-by-step explanation:
using the cosine ratio to find p
cos 45° =
= 
cross- multiplying gives
p × cos45° = 6 → [ cos 45° =
]
p ×
= 6
multiply both sides by 
⇒ p = 6
( third option on list )
Step-by-step explanation:
The factors are x + 2 and x + 6.
Answer:
Part 1:
Yes, the side lengths form a right triangle.
Part 2:
Option d 37.1 cm
Explanation:
We need to use the pythagorean theorem.
In part 1, if the 3 side lengths are a right triangle, then, they must verify:

By the theorem. Then:

They're equal, then the lengths correspond to a right triangle.
For part 2, we need to use again the theorem. In this case:
Answer:
x+1
Step-by-step explanation:
Answer:
the answer is 45 over 6
Step-by-step explanation:
A shortcut is "2 x _____ is 6", which is 3.
Multiply 15 by 3 also, to get 45,
45/6
