Answer:
Please see below :)
Step-by-step explanation:
The slope is just what's in front of the x!
So:
1.) slope = -1/4
2.) slope = undefined
3.) slope = -9
4.) slope = 9/2
Hope this helps!
Important notes:
3 sides 1 angle - COSINE RULE
2 sides 2 angle - SINE RULE
since, the question wants to find the length of BC. In the end we will have 3 sides and 1 angle and use cosine rule
formula of cosine rule:
a² = b² + c² - 2bc Cos A° (to find the length)
Cos A° = b² + c² - a² / 2bc ( to find the angle, if there is given three sides and have to find the angle)
So just substitute,
a² = 13² + 15² - 2(13)(15) Cos 95°
a = 20.6 or 21
Wait, this is simplified because there are no common terms.

Answer:
The answer is "
"
Step-by-step explanation:
Given value:
When we subtract set X - Y it means, that it will give only, that value which is not available on the set Y.
