Using (n-2)180 to find total number of degrees in a 5-sided shape
n= number of sides

(5-2)180=540degrees

So to find x, 100+160+80= 340
540-340=200

So 8x+8+5x+10=200 and solve for x

Answer:

x = 88.463°

Step-by-step explanation:

We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,

$\rm\implies\red{ 0^0 < x < 360^0 }$

Given trigonometric equation :-

$\rm\implies\red{ 1 + 5 sin (x-100^0)=0 }$

Subtracting 1 both sides , we have ,

$\rm\implies 5sin( x - 100^0)= -1$

Divide both sides by 5 ,

$\rm\implies sin( x - 100^0)= \dfrac{-1}{5}$

This equation can be written as ,

$\rm\implies x - 100^0 =sin^{-1}\bigg(\dfrac{ -1}{5}\bigg) \\\\\rm\implies x - 100^0 = -11.53^0 \\\\\rm\implies x = 100^0-11.53^0\\\\\rm\implies\boxed{\bf x = 88.463^0}$

I need to say it in a audio recording so please make it understandable to say in words

Answer:

see explanation

Step-by-step explanation:

Consider perfect squares either side of 60, that is

49 < 60 < 64, thus

$\sqrt{49}$ < $\sqrt{60}$ < $\sqrt{64}$ , that is

7 < $\sqrt{60}$ < 8

60 is closer to 64 than it is to 49

$\sqrt{60}$ ≈ 8 ← integer approximation

What is the answer to 63+x+13=3x,x

Gnoma [55]

$63 + x + 13 = 3x \\ 63 + x + 13 - 3x = 0 \\ combine \: like \: terms \\ - 2x + 76 = 0 \\ - 2x = - 76 \\ \frac{ - 2x}{ - 2} = \frac{ - 76}{ - 2} \\ x = 38$

Multiply (-6y-7)(4y+3) Simplify your answer.

babymother [125]

1st multiply -6y by 4y=-24y^2
2nd, multiply -6y by 3=-18y
3rd, multiply -7 by 4y=-28y
4th, multiply -7 by 3=-21
5th, write all the terms in standard form: -24y^2-18y-28y-21
Combine like terms:-18y-28y=-46y
Put in standard form: -24y^2-46y-21

Final Answer: -24y^2-46y-21
