Find the value of x

Mathematics
2 answers:
zloy xaker [14]3 years ago

Answer:

66

Step-by-step explanation:

EHG is a straight line so it is 180°.

You already know the value of FHG, so you can find the value of 2x.

180° = 48° + 2x

2x = 180° - 48°

    = 132

x = 132° ÷ 2

  = 66

Answer:

66 should be the answer.

Step-by-step explanation:

2x + 48 = 180

2x + 48 - 48 = 180 - 48

2x = 132

2x ÷ 2 = 132 ÷ 2

x = 66

The given trinomial can be factored using the factorization method.
x² - 2x - 24
The middle term should be written is such a way that the sum of two terms is equal to the middle one and their product should be equal to the product of first and third term. So the above expression can be written as
= x² -6x + 4x - 24
= x(x-6) + 4(x-6)
= (x-6)(x+4)
Thus, (x-6)(x+4) is the factored form of the polynomial.
So the correct answer is option B

The parallelogram shown below has an area of 404040 units^2 2 squared.
TEA [102]

Question:

The parallelogram shown below has an area of 40 units squared.

Find the missing base.

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.

However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.

The area of a parallelogram is calculated as thus.

Area = Base * Height

Given that the area = 40 units²

Let's assume the height of the parallelogram is 10 unit.

All you need to do is to plug in these values in the formula above..

Area = Base * Height becomes

40 = Base * 10

Divide both sides by 10

40/10 = Base * 10/10

4 = Base

Hence, Base = 4 units

Or take for instance the height is 5 units.

You'll still follow the simple steps as it is above.

Area = Base * Height becomes

40 = Base * 5

Divide both sides by 5

40/5 = Base * 5/5

8 = Base

Hence, Base = 8 units

What the heck do i do with this

Use the law of cosines to find a: a^2=b^2+c^2-2bc (cos(A))

So to use the given numbers you get: a^2=27^2+45^2-2(27)(45)(cos(53))

Which would come out to equal about 35.94

so a=35.9
