Answer:

Hello! The answer is 60°.

Step-by-step explanation:

As marked by the dashes on each side, the sides are congruent. If the sides are congruent, this means that the angle measures are equal.

Having three equal sides is an equilateral triangle, and the total angle measure sum is 180.

To find the measure of angle y, you will have to divide the total angle measure by the number of angles:

180 ÷ 3 = 60

The measure of angle y = 60°

Answer:

60 degrees

Step-by-step explanation:

Since all three sides are the same length, all three angles must be the same size. This means the triangle is an equilateral triangle

The angles are 60 degrees

X²-10+3x=0 la ecuación es completa o incompleta?

hjlf

Answer:

Yes, the equation is complete.

Step-by-step explanation:

The given quadratic equation, x² + 3x - 10 = 0 is expressed in standard form, ax² + bx + c = 0.

Where: a = 1, b = 3, and c = -10.

Using the quadratic formula:

$x = \frac{-b (+/-) \sqrt{b^{2} - 4ac} }{2a}$

We can solve for its solution by plugging in the values for a, b, and c.

$x = \frac{-b (+/-) \sqrt{b^{2} - 4ac} }{2a}$

$x = \frac{-3 (+/-) \sqrt{(3)^{2} - 4(1)(-10)} }{2(1)}$

$x = \frac{-3 (+/-) \sqrt{9 + 40} }{2}$

$x = \frac{-3 (+/-) \sqrt{49} }{2}$

$x = \frac{-3 + 7 }{2}$ , $x = \frac{-3 - 7 }{2}$

$x = \frac{4}{2} = 2$ , $x = \frac{-10 }{2} = - 5$

Therefore, the solutions of the quadratic equation, x² + 3x - 10 = 0 is:

x = 2, and x = -5
