Can someone teach me step by step

Mathematics
1 answer:
konstantin123 [22]3 years ago
6 0

Answer:

x = 25

Step-by-step explanation:

Since CQ is parallel to BR and intersects the other 2 sides then it divides those 2 sides proportionally, that is

\frac{BQ}{QD} = \frac{RC}{CD} , substitute values

\frac{24}{40} = \frac{15}{x} ( cross- multiply )

24x = 600 ( divide both sides by 24 )

x = 25

Can someone please help me solve this

Here's a little known but very useful factoid:

If they're inversely proportional,
then their product is constant.


Here's how to use it:

-- We're told that Y = 8 when X = 7.
So when y=8 and x=7, their product is 56 .

-- If Y REALLY varies inversely as X, then
their product is ALWAYS going to be 56.

-- So when Y=4, X= (56/4) = 14 .

Angle x and angle y are complementary angles if angle y is 5 times the size of angle x .what is the value of x and y
Ivahew [28]

The values of x and y are 15 and 75, respectively

<h3>How to determine the values of x and y?</h3>

The statements are given as:

  • Angle x and angle y are complementary angles
  • Angle y is 5 times the size of angle x

These mean that

x + y = 90

y = 5x

Substitute y = 5x in x + y = 90

x + 5x = 90

Evaluate the sum

6x = 90

Divide by 6

x = 15

Substitute x = 15 in y = 5x

y = 5 *15

Evaluate

y = 75

Hence, the values of x and y are 15 and 75, respectively
