Answer:
I think it is 8 because all the angles should measure up to 360
Step-by-step explanation:
Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%
The value of measure of ls is 126 degrees.
It is given in the question that the measure of two supplementary angles, ls and lt, are in the ratio of 7:3.
We have to find the value of measure of ls.
Let the measure of two supplementary angles ls and lt be 7x and 3x respectively.
We know that, the sum of measure of two supplementary angles is 180 degrees.
Hence, according to the data given in the question, we can write,
7x + 3x = 180 degrees
10x = 180
x = 180/10
x = 18 degrees
Hence,
mls = 7x = 7*18 = 126 degrees.
