<span>rhythm of the falling rain answered 6 year<span>Given an if-then statement "if p, then q", we can create three related statements: 


A conditional statement consists of two parts, a hypothesis in the “if” clause and a conclusion in the “then” clause. 

For instance, “If it rains, then they will cancel school.” 
“It rains, “is the hypothesis. 
“They will cancel school,” is the conclusion. 

To form the converse of the conditional statement, interchange the hypothesis and the conclusion. 

The converse of “If it rains, then they will cancel school.” is 
“If they cancel school, then it rains.” 

To form the inverse of the conditional statement, take the negation of both the hypothesis and the conclusion. 

The inverse of “If it rains, then they will cancel school” is “If it does not rain, then they do not cancel school.” 

To form the contrapositive of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. 

The contrapositive of “If it rains, then they will cancel school” is “If they do not cancel school, then it does not rain.” 

Summary: 
Statement If p, then q. 
Converse If q, then p. 
Inverse If not p, then not q. 
Contrapositive If not q, then not p. 

If the statement is true, then the contrapositive is also logically true. If the converse is true, then the inverse is also logically true. 

Example: 
Statement If a person is 18 years old, then he is a legal adult. 
Converse If a person is a legal adult, then he is 18 years old. 
Inverse If a person is not 18 years old, then he is not a legal adult. 
Contrapositive If a person is not a legal adult, then he is not 18 years old.</span></span>

HELP ASAP!!! explanation requiredd!

(7x-5)+(3x-15)=180°

10x-20=180

10x=200

x=20

(3x-15) + E = 180

3(20)-15 + E = 180

45 + E = 180

E = 135°

FG = EH = 2(y+1)

In the circle below, EG is a diameter and EF is tangent at E. Suppose mEF = 124°. Find the following. Does anyone know this?
Ludmilka [50]

Answer:

Step-by-step explanation:

If EG is a diameter, then arc EFG is a semicircle and its measure is 180. Arc FG then is 180 - 124 = 56. Since angle FEG is an inscribed angle and the arc it cuts off is arc FG, then the measure of the inscribed angle is half the measure of the arc it cuts off...so angle FEG is 28 degrees. Keep that in mind; we'll need it in a sec.

If HE is tangent to the circle at E, then angle HEG is a 90 degree angle. Adding that to angle FEG will give you angle FEH. Angle FEH = 90 + 28 = 118

Help me do this plz
Rainbow [258]

Answer:

10.25

Step-by-step explanation:

Using the pythagorean theorem

13^2 = 8^2 + (ML)^2

169 = 64 + (ML)^2

Subtract 64 from both sides

105 = (ML)^2

Take the square root of both sides

10.25 = ML
