Answer:
x = 12.5
Step-by-step explanation:
The given triangle is a right angle triangle.
We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.
As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.
So,
cos θ= base/hypotenuse
cos 28=11/x
x=11/cos28
x=11/0.8829
x=12.45
Rounding off to nearest 10
x=12.5
Answer:
The given statement is true.
Step-by-step explanation:
Quadrilaterals are similar if their corresponding sides are proportional.
This statement is true.
Quadrilaterals are similar when
a) corresponding angles are equal
b) the corresponding sides are proportional i,e the ratios of corresponding sides are equal
So, the given statement is true.
Answer: a) 
b) 30
Step-by-step explanation:
Given: The number of new songs that a rock group needs to stay at the top each year is inversely proportional to the year and that the group has been in the industry.
Let x be the number of songs will be needed after 5 years.
Now the inverse variation equation for the given question will be:-
Hence , the number songs will be needed after 5 years = 30
