10.
sam=(4,2)
theater=(-3,5)
11.
it has 4-(-3)=7 kilometers distance in x direction
and has 5-2=3 kilometers distance in y direction
12.
5-9=-4
so restaurant=(-3,-4)
13.
(5-(-4))/2=9/2=4.5
5-4.5=0.5
so seth=(-3,0.5)
⭐️- Remember that slope formula is y=mx+b
1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*
*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
Answer:
39?
Step-by-step explanation:
180-102=78
78/2=39
To determine to measure the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Hope this helps you understand angles in a triangle
