Answer:
30,90
Step-by-step explanation:
because it all adds up to 180
Answer:
a = 10
b = 23
Step-by-step explanation:
if this is a parallelogram
a + 5 = 15
a = 10
3b + 111 = 180
3b = 69
b = 23
Answer:
The angle θ, that the device needs to scan is 16.795°
Step-by-step explanation:
Here we have
Height of room = 11 ft
Width of room = 15 ft
Length of room = 18 ft
Position of camera = 6 inches below the ceiling = 11 ft - 6 in = 126 in = 10.5 ft
Distance from camera to edge of long side of the room is given by the following relation;
Long edge of angle = √((18 ft)²+(10.5 ft)²) = 20.839 ft
Shorter edge of angle = √((15 ft)²+(10.5 ft)²) = 18.31 ft
Opposite side of required angle = √((18 ft)²+(15 ft)²) = 23.431 ft
Therefore, by cosine rule, we have
a² = b² + c² - 2·b·c·cos A
We therefore put our a as the opposite side of the required angle, A so we can easily solve for it
our b and c are then the other two sides
23.431² = 20.839² + 18.31² - 2×20.839×18.31×cosA
∴ cos(A) = (23.431² - (20.839² + 18.31²))÷(2×20.839×18.31)
cos(A) = 220.5/763.12418 = 0.29
A = cos⁻¹0.29 = 16.795°
The angle θ, that the device needs to scan = 16.795°.
Data can be analysed in a situation when one wants to know how increase in price has an effect on purchasing power.
<h3>What is a trend?</h3>
It should be noted that a trend simply means the general direction or price over a period of time. A situation when I need data was when I wanted to know how increase in prices had an effect in one's purchasing power.
To get the data, I had to take the prices of goods when there was no inflation and prices when there was inflation and how they had an impact on income.
It showed that an inverse relationship existed as an increase in prices had a negative impact on one's purchasing ability.
