A = 3, b = 6 $a^2 + b^2 = c^2 \\ 3^2 + 6^2 = c^2 \\ c^2 = 9 + 36 = 45 \\ c = \sqrt{45}$ The last is exact in un-simpified form $c = \sqrt{45} = \sqrt{9} * \sqrt{5} = 3 \sqrt{5}$ Simplified radical form
$3 \sqrt{5} = 6.71$

Geometry - Isosceles & Equilateral Tirangles<br><br> Solve for x *

padilas [110]

Answer:

x = 11

Step-by-step explanation:

Here, the two angles given are equal to each other.
So, it is an isosceles triangle.
Therefore, the sides opposite to the two angles are equal.
Therefore,

(x + 13) ft = 24 ft

or, x ft = 24 ft - 13 ft

or, x ft = 11 ft

or, x = 11

△ABC is a right triangle with right angle C. Side AC is 6 units longer than side BC . If the hypotenuse has length 52–√ units,

Evgesh-ka [11]

Answer:

AC = 7.12 units

Step-by-step explanation:

A right triangle has two legs and a hypotenuse. The hypotenuse is opposite the right angle. As Angle C is the right angle, then the triangle can be constructed as shown in the picture attached. The sides of the triangle have a relationship known as the Pythagorean Theorem a² + b² = c². In the theorem, the legs of the triangle are a and b while the hypotenuse is c. Substitute a = x, b = x+6, and c = √52. Simplify and solve.

a² + b² = c²

x² + (x+6)² = √52²

x² + x² + 12x + 36 = 52

2x² + 12x - 16 = 0

You can use the quadratic formula to solve by substituting a = 2, b = 12, and c = -16.

The quadratic formula is $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$ .

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-12+/-\sqrt{12^2-4(2)(-16)} }{2(2)}=\frac{-12+/-\sqrt{144+128} }{4)}$

$\frac{-12+/-\sqrt{272} }{4}=\frac{-12+/-16.5 }{4} = 1.12, 7.13$

Only 1.12 is a solution since 7.13 will not satisfy the Pythagorean theorem

Side AC is 6 units longer than side BC. This means x = BC and AC = x + 6.

AC = 1.12 + 6 = 7.12

Select from the drop-down menu to correctly complete the statement.

Usimov [2.4K]

The true statement is that: if you cannot get from one term to the next by adding or multiplying by a constant value, the sequence is neither arithmetic nor geometric

<h3>How to determine the true statement</h3>

A progression can either be arithmetic, geometric or neither.

When the progression has a common difference (gotten by addition), then the progression is arithmetic
When the progression has a common ratio (gotten by multiplication), then the progression is geometric

If the above are not true, then the sequence is neither arithmetic nor geometric
