Answer:
35 degrees.
Step-by-step explanation:
In order to find an angle in a triangle we need to know the other two angles, because the angles in a triangle all add up to 180 degrees. So, knowing two will get us the other one. In this case, we know two angles. One of them is 55, and the other, since it is a right triangle, is 90. So the two angles we know are 55 and 90. Using that all angles in a triangle add up to 180, we can use
55 + 90 + x = 180
145 + x = 180
x = 35
The answer is 0=24 hope this helped
Answer:
x2-5x-8=0
Step-by-step explanation:
Two solutions were found :
x =(5-√57)/2=-1.275
x =(5+√57)/2= 6.275
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-5x-8
The first term is, x2 its coefficient is 1 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 1 • -8 = -8
Step-2 : Find two factors of -8 whose sum equals the coefficient of the middle term, which is -5 .
-8 + 1 = -7
-4+ 2 = -2
-2+ 4 = 2
-1 + 8 = 7
