60 degrees

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.

So if you add 40 + 90 + x = 180

You get 130 + x = 180

If you subtract 180 - 130

You get 60.

If I didn’t explain it good enough, let me know so I can explain it better.

If this helped, pls mark branliest.

Solve this problem please

Hi, Ptaverez1! :)

First we must length of an individual square; This can be achieved by using the formula for the area of a square:
$l^2$
$l=Length$

Lets input the information we already know:
$l^2=42.25$
Take square root.
$l=\sqrt42.25$
$l=6.5$

The length of an individual square tile is 6.5 ft.

Since they're are 9 tiles and the porch in a square, I can conclude that the measurements for the porch are 3 tiles by 3 tiles (as 3*3=9; using the formula for the area of a square.)

Since the length of the porch is 3 tiles, we must multiply the individual tiles piece length by 3:
$3*6.5$
$=19.5$

The formula for the perimeter of a square is:
$l*4$
$l=length$

Lets input the information we know:
$19.5*4$
$=78$

The perimeter of the porch is 78 feet²

Hope this helps.

Use the digits 0-9, find out how many 4 digit numbers can be configured based on the stated conditions:

Alexeev081 [22]

A) On the first place we can put 9 digits, on the second 9, on the third place 8 and on the last place 7 ( because no digits can be repeated ):
9 · 9 · 8 · 7 =4536 numbers
b) There are 5 odd digits can be repeated. So:
5 · 10 · 10 · 5 = 2500 numbers
c) On the first place we can put:5,6,7,8,9 (5 digits) On the last place is just one (0), because the number must be divisible by 10:
5 · 10 · 10 · 1 = 500 numbers
d) on the first place we can put 2 digits ( 1, or 2 - there are no 4-digit numbers starting with 0). The last digit must be even, but the order can be:
X - odd - odd - even 2 · 5 · 4 · 5 = 200
X - odd - even - even 2 · 5 · 5 · 4 = 200
X - even - odd - even 2 · 5 · 5 · 4 = 200
X - even - even - even 2 · 5 · 4 · 3 = 120
Finally: 200+ 200 + 200 + 120 = 720 numbers

natima [27]

Answer:

Step-by-step explanation:

It says that Maya makes one dollar more for each book that she sells so if she sells 13 books, she will make 13 dollars more than her weekly earning which is 43 dollars. So to find the answer, you would need to add 13 + 43 which would equal 56 dollars.
