Answer:  " 50 " .

_____________

 →  " m∡EDH = 50 ° " .

_____________

<u>Step-by-step explanation</u>:

Note that "5x" and "4x" add up to "90 degrees" ; these are "complementary angles" —meaning that their measurements add up to "90 degrees"—in this case, they form a "right angle" (which is a "90 degree angle".).

_____________

So:   " 5x + 4x = 90 " ; Solve for "5x" ;

                               which is the:  " measure of angle EDH " ;

                                                      [i.e. " m∡EDH "] ;

 → 5x + 4x = 9x ;

_____________

    →  9x = 90 ;

Divide each side of the equation by "9" ;

  to isolate "x" on one side of the equation;

  & to solve for "x" ;

 → 9x / 9 = 90 / 9 ;

to get:

  →  x = 10 ;

_____________

Let's check our answer:

 9x  =? 90 ? ;

→ 9 * 10 =? 90 ? Yes!

_____________

Let us further check our answer:

_____________

"4x + 5x = 90 " ;

→ (4*10) + (5*10) =? 90 ? ;

    → 40 +  50 = ? 90 ? ; Yes!

_____________

Now, since we know that:  " x = 10 " ;

 we can solve for "5x" ; which is the: " m∡EDH " ;

→ m∡EDH =  " 5x "  = " 5* (10) = 50 ° " .

_____________

Hope this is helpful!

Best of luck to you!

Answer:

a) 36°

b ) 18°

Step-by-step explanation:

The formula is given as:

The measure of each exterior angle =360°/n, where n = number of sides of a polygon.

a) decagon

Decagon = 10 sides

Hence, the measure of each exterior angle = 360°/10

= 36°

b) 20-gon

20-gon = 20 sides

Hence, the measure of each exterior angle = 360°/20

= 18°

a man is four times as old as his son in five years time he will be three times as old as his son what is the present age of the
Oksi-84 [34.3K]

I would start by setting up a chart like I did below.

Label one column age now and the other age in 5 years.

Since we don't know the son's age we use x.

We do know that the man's age is 4 times the son's age.

So the man's age will be 4x.

In the age in 5 year column, we add 5 to their current ages.

Now set up our equation.

Since it says "in five years" we use information in second column.

In 5 years time, he, "4x + 5", will be, equals,

3 times as old as his son, "3(x + 5)".

So we have 4x + 5 = 3(x + 5).

Solving from here, we find that x = 10.

So the son is 10 and the man is 4 times his age or 40.

How do you divide 2/10 by 3/4? Please help!
Ray Of Light [21]

Answer:

8/30

Step-by-step explanation:

Dividing fractions is almost the same as multiplying to do it you just have to flip the second fraction and change the division sign to a multiplication sign like this,

2/10×4/3

then from there, you have to multiply the top numbers and the bottom numbers

2×4=8

10×3=30

then put them together

8/30
