Answer:
6 brochures
Step-by-step explanation:
Each brochures is 23 centimeters wide.
The table is 1.5 meters wide.
To know how many brochures can be placed side by side on the table first you have to calculate how many centimeters there are in 1.5 meters wide.
One meter equals 100 centimeters.
Therefore in 1.5 meters there are:
centimeters.
Now we must calculate in how many parts of 23 cm can be divided 150 cm.
To do this we made the division of 150 between 23
This means that up to 6 brochures of 23 cm can be placed side by side on the table
Given:
In the given triangle,
With respect to y, Perpendicular = 10 cm and Base = 8 cm
To find the value of y.
Formula
By Trigonometric Ratio we get,
Now,
Putting the values of perpendicular and base we get,
or,
or,
Rounding off to the nearest tenth, we have;
Hence,
The value of y is 51.3°.
