The measure of an angle is 30 degrees less than half the measure of its supplement. what is the measure of the angle? a: 10 b: 40 c: 90 d: 140

The concept of supplementary angles is :

Sum of supplementary angles =180 degrees

Now let us say one of the supplementary angle measures x degrees.

finding expression for second angle,

half the measure of x is 0.5x

30 degrees less means subtracting 30 so we have 0.5x-30

now the two angles are x and 0.5x-30

Adding the two will be equal to 180 , so forming an equation,

adding 30 on the right side,

dividing both sides by 1.5

x=210/1.5 = 140

So first angle is 140

our angle is 0.5x-30 which is 40 degrees

Answer is 40 degrees

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
