Answer: It looks like you are missing the question here. Most of the time in this type of questions, we are looking for the 3rd angle.
Let's assume that you need the 3rd angle.
There are 180 degrees in a triangle. We know 2 of the angles, so by subtracting them from 180 we can find the 3rd angle.
180 - 45 - 60 = 75
Angle C is 75 degrees. In the similar triangle Angle R is also 75 degrees because the corresponding angles are congruent.
Answer:
g(x) = 
Step-by-step explanation:
We can see that the graph is beginning at (-2; 0), then the domain of defintion needs to be [-2; +inf], the only function that satisfies this is that function!
(7x+2)(20-3x/4) = 140x + 40 - 21x²/4 - 3x/2 = -21/4 x² + 138 1/2 x + 40
this is one of those multiplications that doesn't make the result look any simpler...
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
