Help please!!! Find the measure of A in the picture below.

Answers

Answer:

Step-by-step explanation:

If you draw in BD, you can show that triangle BCD = triangle BAD by SSS

That means that <A = <C  parts of congruent parts are congruent.

<A + <C + 115 + 71 = 360

<A + <C + 186 = 360            All convex quadrilaterals have  4 interior angles that add to  360 degrees

<A + <C = 360 - 186

<A + <C = 174

So call <A  and < C = x

x + x = 174

2x = 174

x = 174 / 2

x = 87

<A = 87

x+3>70

Which choice is equivalent to the quotient below?
40/8

Answers

Answer:

A.

Step-by-step explanation:

You simplify the square root until you narrow it down to the square root of 5.

The quotient of expression of √40/√8 is √5 which is correct option (A).

What is expression?

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ √40/√8

Factor of √40 = √8×√5

⇒ (√8√5)/√8

Cancel out of√8

⇒ √5

Hence, the quotient of expression of √40/√8 is √5.

How did labor unions and African Americans intersect during the era? What role did black people play in strikes? Points to consider:Although the Knights of Labor allowed black membership, by the 1890s the organization had lost influence to the American Federation of Labor. Founded in 1886, the AFL was ostensibly open to all skilled workers, but most of its local craft unions barred women and black tradesmen. In contrast, the United Mine Workers (UMW), formed in 1890, encouraged black coal miners to join the union rather than serve as strikebreakers. By 1900 approximately 20,000 of the 91,000 members of the UMW were black men. The Industrial Workers of the World, a revolutionary labor organization founded in 1905, brought black laborers and white laborers together. In 1869 a Baltimore ship caulker, Isaac Myers, organized the National Colored Labor Union, which lasted for seven years. Black stevedores periodically went on strike in Charleston, Savannah, and New Orleans. The Longshoremens Protective Union in Charleston won several strikes in the 1870s. In Nashville in 1871 black dockyard workers went on strike, demanding 20 cents an hour.2. What was the educational debate between Booker T. Washington and W. E. B. Du Bois?
