Answer:
i wrote this as a decimal so um i hope this at least helps :). 1.75
Step-by-step explanation:
It's a simultaneous equation:
Steps:
1.Number the equations..
a+b=77 -1
a-b=13 -2
2. Choose what variable you want to use. In this case I would use the "b". Since the signs in front of the "b's" are different, add the two equations together
a + b = 77
+ + +
a (-b) = 13
Which gives;
2a = 90
Then solve to find a:
2a=90
a= 90/2
a=45
3.Then plug the "a" value into any of the original equations to find the "b" value. I would use equation 1 since the all the variables are positive.
a + b = 77
(45) + b = 77
b=77-45
b=32
4.Solution
a=45
b=32
Answer:
D. <3 and <7
Step-by-step explanation:
Corresponding angles are angles that are on matching sides and that are cut by a transversal.
Hope this helps!
Answer:
They are not similar.
Step-by-step explanation:
In triangle ABC, the angle we are given is in between the two defined sides(AB and BC with angle B). If these triangles were similar, we would see this with the SAS postulate.
In triangle KLJ, the angle is not in between the two sides, so they are not similar according to any of these two postulates.
