There are 270 degrees in a circle of a 3/4 turn.
Answer:
-1.25, 2, 3.5
Step-by-step explanation:
(x-2)(2x-7)(4x+5)=0
(2x^2-7x-4x+14)(4x+5)=5
from now on you know that either
(2x^2-7x-4x+14)=0 or
(4x+5)=0
By solving the first eqation (2x^2-7x-4x+14)=0
you get x = 2 or 3.5
By solving the second equation (4x+5)=0
you get x = -1.25
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.

<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
5ab * (-a) + 5ab * (-5b) + 5ab * 3
Benzer terimleri her iki tarafta birleştirmek:
10x = 15x + 65
-5x = 65
x'i izole etmek:
65/-5 = -13
x = -13
