Answer:
As they triangles are congruent, we can say that, angle A = angle O
So, angle A = 105+25 =130
A = 180 - 130 = 50° all angles in a triangle add up to 180)
Soo 50° is the answer,
I'm not too sure about it but I think this is correct, hope this helps, correct me if I'm wrong....
The average is found by adding all the temperatures together, then dividing by the number of days.
Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.
The total for the first four days was : 56 + 60 + 79 + 70 = 265
The fifth day is 315 - 265 = 50 degrees.
Answer:
27
Step-by-step explanation:
Let x be the number,
2x - 6 = 48
2x = 48 + 6
2x = 54
x = 27
When x = 4 and we have 12+x/4+x we can substitute 4 in for x.
12+4/4+4 = 12 + 1 + 4 = 17
