Answer:
adjacent angles are 50° and 130°
Step-by-step explanation:
The sum of all 4 angles in a parallelogram is 360°, so the fourth angle must be ...
360° -310° = 50°
Adjacent angles are supplementary, so the other two angles must be ...
180° -50° = 130°
The angles in the parallelogram are either 50° or 130°. Adjacent angles are different.
1 3/10·b=39
(1·10+3)·b/10=39
13b/10=39
13b=39·10
13b=390|:13
<u>b=30</u>
<em>Answer: 30</em>
I think you would most likely add all of them well I think
we are given
x^2-4x-5
we can use formula
x^2-(a+b)x+ab=(x-a)(x-b)
so, we have
a+b=4
ab=-5
now, we can solve for a and b
and we get
a=5, b=-1
now, we can plug it in formula
x^2-4x-5=(x-5)(x+1) ............Answer
