Let first and second angle be x
As we know the sum of all angles of a triangle is 180 by angle sun property
So 1x +2x +65=180
3x +65 =180
3x =180-65
3x=115
X=115/3
So angle 1=x =115/3
Angle 2=2x =230/3

Hope it will help you

Step-by-step explanation:

Angle sum property :

1x + 2x + 65 = 180

3x + 65 = 180

3x = 180 - 65

3x = 115

x = 115/3

x = 38.333

2x = 76.666

Sergio [31]
Rememeber, you can do anything to an equation as long as you do it to both sides


4=8-3h
minus 8 both sides
-4=-3h
divide both sides by -3
-4/-3=h
4/3=h
h=4/3 or about 1.333333333333333333333333333

I need help please?!!!!
shusha [124]

Answer:

n = -6

Step-by-step explanation:

-3n + 9 = 27 (Given)

-3n + 9 - 9 = 27 - 9 (Subtraction Property of Equality)

-3n = 18 (Simplify)

\frac{-3n}{-3} = \frac{18}{-3} (Division Property of Equality)

n = -6 (Simplify)

Anyone know how to do this? i dont know how to get the whole angle including 44 and P
Ganezh [65]

Answer:

C

Step-by-step explanation:

The total circumference = 5*2 pi = 10pi

You are trying to find (360-44)/360 of the circumference, which simplifies to 79/90.

79/90 *10pi =

79pi/9, which is C

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is stu
Mashcka [7]

The account that recorded a greater percentage change in amount of money over the previous year is year 4

<h3>Part A: Is the amount of money in account A increasing or decreasing?</h3>

The exponential function is given as:

f(x) = 9628 * (0.92)^x

An exponential function is represented as:

f(x) = ab^x

If b is less than 0, then the function is an increasing function.

So, the function f(x) = 9628 * (0.92)^x is a decreasing function.

The percentage of decrement is then calculated as:

r =1 - b

This gives

r = 1 - 0.92

Evaluate

r = 0.08

Express as percentage

r = 8%

Hence, the percentage of decrement is 8%

<h3>Part B: The account that recorded a greater percentage change in amount of money over the previous year</h3>

r  1 2 3 4

g(r) 8,972 8,074.80 7,267.32 6,540.59

As a general rule:

As the number of years increases, the percentage change increases

Hence, the account that recorded a greater percentage change in amount of money over the previous year is year 4
