A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum: 
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs 
15^2=9^2+B^2 
225=81+B^2 
225-81=B^2 
144=B^2 (square root both sides)

Step-by-step explanation:

Given:

∠DEF = 117°

∠DEG = (12x + 1)°

∠GEF = (5x - 3)°

Find:

value of x

Computation:

∠DEF = ∠DEG + ∠GEF

117° = (12x + 1)° + (5x - 3)°

NEED TO SHOW ALL WORK) For each of the equations given below, use the triangle method to solve for the
Lelechka [254]

Answer:

1) a=\dfrac{F}{m}

2) m=\dfrac{p}{v}

Step-by-step explanation:

1) The given equation is

F=ma

We need to solve this for a.

In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

F=ma

a=\dfrac{F}{m}

m=\dfrac{F}{a}

Therefore, the required answer is a=\dfrac{F}{m}.

2) The given equation is

p=mv

We need to solve this for m.

In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

p=mv

m=\dfrac{p}{v}

v=\dfrac{p}{m}

Therefore, the required answer is m=\dfrac{p}{v}.

Solve each equation
Darya [45]

Answer:

r= 0

r= 1

b= -3

x= -3

Step-by-step explanation:

4r-8r=0

-4r=0

r=0

-15=-8r-7r

-15= -15r

r=1

3b+7-1=-3

3b= -3-7+1

3b= -9

b= -9/3

b=-3

3x+1-6x=7

-3x= 7-1

-3x= 6

x= -6/3

x= -3
