Let x represent the measurment of an acute angle in degrees. the ratio of the complement of x to the supplement of x is 2: 5. gu

Nadusha1986 [10]

Ratio of complement of x : supplement of x
2 : 5
⇒ 2 times the supplement of x will be equal to 5 times the complement of x

5(90 - x) = 2 (180 - x)
450 - 5x = 360 - 2x
5x - 2x = 450 - 360
3x = 90
x = 30°

Complement of x = 90 - x = 90 - 30 = 60
Supplement of x = 180 - x = 180 - 30 = 150
Ratio:
60 : 150
60 ÷ 30 : 150 ÷ 30
2 : 5 (checked)

- Higher Order Thinking A rectangular poster has

DaniilM [7]

Answer: 36 centimeters.

Step-by-step explanation:

Given : Area of a rectangular poster = 504 square centimeters.

The width of the poster is 14 centimeters.

We know that area of rectangle :-

$\text{Area= length x width }$

Let l be the length of the poster .

Substitute the above values into this , we get

$504=\text{l}\times 14$

i.e. $504=14\text{l}$

Divide both sides bby 14 , we get

$l=36$

Hence, the length of the poster = 36 centimeters.

Find the value of y.

Snowcat [4.5K]

Answer:

125

Step-by-step explanation:

You can find the interior angle next to the angle with the value of 100, because a straight line has an angle of 180, so that angle would be 80. You can do the same with the interior angle next to 135, with that angle having a value of 45.

The interior angles of a triangle always have the sum of 180, so to get the last interior angle add 80+45 and then subtract that from 180. That angle would be 55.

To get Y take the value of the interior angle subtract 55 from 180, which would be 125.
