Answer:
139 degrees
Step-by-step explanation:
Supplementary angles mean that the sum of the two angles should add up to 180 degrees. Since one of the angles is given, 41 degrees, and you know that the sum should be 180 degrees, you are able to find the measure of the unknown angle QRS.
41 + QRS = 180
QRS = 139 degrees
N= numbers
x= x-ray
4 unknown number equal a unknown amount of x-rays mutiplyed but 5-unknow number.
x can stand for anything and so can n
Answer:
line 1 intersects line 4
Step-by-step explanation:
If line 2 intersects 1 and 3, but 1 does not intersect 3, then lines 1 and 3 are parallel.
Similarly, if line 3 intersects lines 2 and 4, but 2 does not intersect 4, then lines 2 and 4 area parallel.
If 1 and 3 are parallel, and 2 and 4 are parallel, then the fact that 2 intersects 3 means 1 intersects 4.
The answer is A. I like to use SohCahToa to help me out. The S would be Sin. And from there its oposite (8.5) over adjacent (x). hope this helps :)
