Answer:

Step-by-step explanation:

The formula for intersecting chords creating which create the limits of arcs and associated angles is

<HES = 1/2 (ARC HS + ARC GF)

<HES = 1/2 (ARC 51 + ARC 195)

<HES = 1/2 (246)

<HES = 123

What that tells you is that <GEF = the same thing because <HES and <GEF are vertically opposite.

Now I am going to assume that <HES = 16x + 11. This is not a sure thing, but I assume it is what is intended.

16x + 11 = 123 Subtract 11 from both sides

16x = 123 - 11

16x = 112 Divide by 16

x = 112/16

x = 7

Find the length of the second leg of the triangle round to the nearest hundredth

horsena [70]

Answer:

$\displaystyle \frac{3\sqrt{230}}{5}$

Step-by-step explanation:

Use the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 9,7^2 + b^2 = 13,3^2; \sqrt{82,8} = \sqrt{b^2} \\ \\ \frac{3\sqrt{230}}{5}\:[or\:9,0994505329...] = b$

So, you have this:

$\displaystyle 9,1 ≈ b$

Which of the following is NOT true? Question 19 options: (3x2y5)3=27x6y15 (1000x12y20z−3)0=1 52‾‾√3=523 42×43= 165

bixtya [17]

Answer:

Step-by-step explanation:

Lets try to simplify each to check which one is incorrect so it will be NOT true

first one is :

distribute the exponent so :

$(3x^2y^5)^3 =3^3x^{2*3}y^{5*3}$

$27x^6y^{15}$ CORRECT

Second one is :

$(1000x^{12}y^{20}z^{-30})^{0} =1$

CORRECT because anything raised to exponent 0 is 1 .

Last one is :

$4^2 *4^3 = 4^{2+3}\\=4^{6}\\=(4)^{2*3}\\=16^{3}$

so Last is INCORRECT
