Answer: 141.7 ct
Step-by-step explanation: It's quite easy to notate this. Just move the decimal point two units to the right, and there's your notation!
Answer:
a. x = 5, AB = 14, BC = 8
Step-by-step explanation:
✔️Both triangles are similar, therefore their side lengths are proportional to each other.
Thus:

Cross multiply


Collect like terms


✔️AB = 2x + 4
Plug in the value of x
AB = 2(5) + 4
AB = 14
✔️BC = x + 3
Plug in the value of x
BC = 5 + 3
BC = 8
Answer:
1.
Step-by-step explanation:
I am assuming you want to simplify this.
cos^2 x + sin^2 x = 1 and
csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1
So the answer is 1/1 = 1.
