Answer:

<h3><X = 63</h3>

Step-by-step explanation:

USing SOH CAH TOA

sin theta = opposite/hypotenuse

sin <X = WV/VX

sin <X = 8/9

<X = arcsin(8/9)

<X = arcsin(0.8889)

<X = 62.7 degrees

Hence the value of x is approximately 63degrees

Which products result in a difference of squares or a perfect square trinomial? Check all that apply.

tiny-mole [99]

Answer:

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

$(7x+4)(7x+4)=49x^2+56x+14$

Step-by-step explanation:

$(7x+4)(7x+4)=(7x+4)^2$ ( using $(a+b)(a+b)=(a+b)^2$ )

$=(7x)^2+2(7x)(4)+4^2$ ( using $(a+b)^2=a^2+2ab+b^2$ )

$=7^2x^2+56x+16$

$=49x^2+56x+14$

Therefore $(7x+4)(7x+4)=49x^2+56x+14$

which is a perfect square trinomial

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. In a perfect square trinomial, two terms will be perfect squares.

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

$(7x+4)(7x+4)=49x^2+56x+14$

A factory produced 150 tons of steel in one year. The next year, the output increased to 180 tons. What is the percentage increa

nirvana33 [79]

The amount of increase is (180 - 150) = 30 tons.

The increase as a part of the original amount is 30/150 = 0.2

To change a decimal into a percent,
move the decimal point 2 places that way ===> .

0.2 = 20%

Answer:

AOB:180°

ZOB:43°

XOY: 24°

AOY:93°

YOZ:44°

Step-by-step explanation:

You first figure out what x is by adding a,b,c which is 136 from 180.

then you will get 44 which is x. From there you just add the angles that they want you to together and boom answers.
