Solve for x in the diagram

Mathematics
1 answer:
Aliun [14]3 years ago
4 0

Answer:

x=12

Step-by-step explanation:

The two angles shown are complementary angles, so the add to 90 degrees

x+42 + 3x = 90

Combine like terms

4x+42 = 90

Subtract 42 from each side

4x+42-42 = 90-42

4x = 48

Divide by 4

4x/4 = 48/4

x = 12

What expression is equivalent to 7sqrtx^2/5sqrty^3​
V125BC [204]

Answer:

Step-by-step explanation:

Sounds as tho' possible answer choices were listed.  Please, share them without being asked to do so.  Thank you.

 7√(x²)          7√(x²)

------------- = ----------------------

  5 √(y³)        5√( y^(3/2) )

We want to get the fractional exponent out of the denominator.  To do this, multiply both numerator and denominator by y^(1/2):

 7√(x²)          7√(x²)                y^(1/2)      7√(x²)·y^(1/2)       7x√y

------------- = --------------------- * ----------- = --------------------- = ----------

  5 √(y³)        5√( y^(3/2) )       y^(1/2)        5 √(y²)                  5y

This is the final answer.  We have succeeded in removing radicals / fractional exponents from the denominator.

Cooper bought a serving platter originally priced at $20 but on sale for 50% off. After 10% sales tax, what was the total cost?
Gelneren [198K]

Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows:  1.10 ( 0.50*$20), or $11.00.


0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11

If sin theta = 2/3, which of the following are possible
Ira Lisetskai [31]
Sin ø = opposite/hypotenuse = 2/3, cos ø = adjacent/hypotenuse = ?/3, tan ø = opposite/adjacent = 2/?, sec ø = 1/cos ø

to solve ?, Pythagorean theorem must be applied
hypotenuse^2 = adjacent^2 + opposite^2

Manipulating the equation to find the adjacent value = ?

adjacent = sqrt(hypotenuse^2 - opposite^2) = sqrt(9-4)
adjacent = sqrt(5)

so cos ø = sqrt(5)/3, tan ø = 2/sqrt(5) and sec <span>ø = 3/sqrt(5) since the value is positive the possible equivalent trigonometric function should be positive, the answer should be b </span>
