What is the solution set of x2 + 5x- 5 = 0? oss-355 S +385 o sus S* o {stay -S-345 , 30 O S=5+375 5+3/5 2 0 --375 -5 +385 2
jolli1 [7]

Given the quadratic equation:

x^2+5x-5=0

Using the general solution for quadratic equations:

ax^2+bx+c=0\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

From the problem, we identify:

\begin{gathered} a=1 \\ b=5 \\ c=-5 \end{gathered}

Then:

x=\frac{-5\pm\sqrt{25+20}}{2}=\frac{-5\pm3\sqrt{5}}{2}

And the solution set is:

\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]

Find x<br><br> May I please receive help?
NikAS [45]

Answer:

x = 63°

Step-by-step explanation:

See the attachment

The measure of the angles in a triangle = 180 .  If the sides of a triangle are congruent, then the base angles are equal.  So in the triangle with the 72°, you have another angles = 72°.  Looking at the same triangle, 72° + 72° + part of the right angle = 180°. Do the math!  72° + 72° = 140°; 180° -144° = 36° (this is the measure of the piece of the right angle that is in the triangle with the 72° angle..   So the other part of the 90°(right angle) = 90° - 36° = 54°.

Now to solve for x:  You know that if the sides are congruent in a triangle, then the base angles are equal. Thus this triangle angles are x, x, and 54°.

You know that a triangle = 180°, so x + x + 54° = 180°; 2x +54° = 180°;           2x = 126°; x = 63°
