Answer:
168
Step-by-step explanation:
Answer:
60 degrees
Step-by-step explanation:
Since all the sides are congruent it is an equilateral triangle and all equilateral triangles have angles of 60 degrees.
Another way to solve it is knowing that if all sides are congruent that means all angles are congruent. Then doing 180/3 because all triangles have 180 degrees and there are three equivalent angles.
Answer:
Step-by-step explanation:
(5x+1)²>(2x+2)²+(4x)²
25x²+10x+1>4x²+8x+4+16x²
5x²+2x-3>0
5x²+5x-3x-3>0
5x(x+1)-3(x+1)>0
(x+1)(5x-3)>0
x+1=0,gives x=-1
5x-3=0,gives x=3/5
x >0(because 4x should be >0)
side is always positive.
so x>3/5
again 5x+1<2x+2+4x
5x-6x<2-1
-x<1
x>-1
x=all real values >3/5
Answer: Any fraction with a positive numerator and a negative denominator
Step-by-step explanation:
A counterexample in math refers to when a condition is satisfied but the result is not the conclusion that the statement said it would lead to.
In this instance, the statement is that if the numerator of the fraction is larger than the denominator, the result will be greater than 1.
If the numerator is positive and the denominator is negative then the numerator is larger than the denominator because all positive numbers are larger than negative numbers on the number line. However, the result will always be less than 1.
For instance, take the following fractions;
In each case the numerator was larger than the denominator but the result was always less than 1.
Answer:
the fourth
Step-by-step explanation:
Complementary means that the sum of two angels equals to 90°
so LKM and MKN because they're both 45° and the sum is 90°
