An outside angle is equal to the sum of the two opposite inside angles.

Set up the equation to get:

6x = (x+40) + (3x+10)

Simplify the right side:

6x = 4x + 50

Subtract 4x from both sides:

2x = 50

Divide both sides by 2:

x = 50/2

x = 25

Now you have X you can solve for each angle:

6x = 6*25 = 150

(x+40) = 25 + 40 = 65

(3x +10) = 3(25) +10 = 75 + 10 = 85

Im stuck on this problem. Please explain how you got your answer​
klemol [59]

The function y=0.3^x represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.

<h3>Population Growth Equation</h3>

The formula for the Population Growth Equation is:

P_f=P_o*(1+\frac{R}{100}) ^t

           

Pf= future population

Po=initial population

r=growth rate

t= time (years)

growth or decay factor =  (1 ±r)

When 1+R  > 1, the equation represents growth, while 1+R < 1 the equation represents decay.

The question gives:

y=0.3^x, then

Pf=y

Po= 1  

(1+\frac{R}{100}) =0.3 , thus

(100+R}) =30\\ \\ R=-100+30\\ \\ R=-70

r= -70%= -0.7

decay factor= (1-0.7)=0.3

Therefore,

1+R will be = 1+(-0.7)=1 - 0.7 =0.3

When 1+R >1, the function represents exponential growth.

If a is a negative number, then a(1/a) is equal to -1. If a is a negative number and b is a negative number, then product ab is
Firdavs [7]

Both claims are false. In fact, a and \frac{1}{a} are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

a \cdot \dfrac{1}{a} = 1 \quad\forall a \in \mathbb{R}

So, it doesn't matter if a is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

(-2) \cdot \dfrac{1}{-2} = \dfrac{-2}{-2} = 1

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:

  • (+) \cdot (+) = (+)
  • (+) \cdot (-) = (-)
  • (-) \cdot (+) = (-)
  • (-) \cdot (-) = (+)

So, the multiplication of two negative numbers is a positive number.

In the figure, ∠1 ≅ ∠2, ∠3 ≅ ∠4, and . You can justify the conclusion that ∠TKL ≅ ∠TLK by stating _____
VladimirAG [237]
From the question, we know that we will be looking at <3, <4, and angles TKL and TLK. That being said, since <3 is congruent to <4, that means that angles TKL and TLK, which are each supplementary to either angle 3 or 4, are congruent because, since angles 3 and 4 are congruent, they are congruent because the supplements of congruent angles are congruent.
