Its an equilateral triangle so all sides are equal.

2x + 5 = 4x - 1
5 = 2x - 1
6 = 2x
3 = x

Do you get it?

Simplify the radical expression.. square root of 128

Vaselesa [24]

Hello,

first we have to descompose the number:

128 | 2
64 | 2
32 | 2
16 | 2
8 | 2
4 | 2
2 | 2
1

So:
$128= 2x2x2x2x2x2x2 \\ 128=2^{6} *2$

Therefore:
$\sqrt{128}= \sqrt{2^{6} *2}$

You must know these properties:

$\sqrt{a*b} = \sqrt{a} * \sqrt{b}\\ \\ \sqrt[b]{x^a}= x^{ \frac{a}{b}}$

then:

$\sqrt{2^{6} *2} \\ =\sqrt{2^{6}}*\sqrt{2} \\ =2^{ \frac{6}{2}}*\sqrt{2} \\ =2^3*\sqrt{2} \\ \boxed{=8*\sqrt{2}}$

Find the measure of each angle indicated.

Brilliant_brown [7]

Answer:

90 degrees

Step-by-step explanation:

Sum of the angles in a triangle = 180°

Opposite angles are equal

For two parallel lines and a transversal,

corresponding angles are equal, and

alternate angles are equal.

45+45=90.

180-90=90

Plus, you can see that the angle forms a perfect 90 degree angle.
