Step-by-step explanation:
Given that 
is a right angled triangle.
and
Kindly refer to the attached image of in which all the given angles are shown.
To find:
sin(38°) = ?
a) cos(38°)
b) cos(52°)
c) tan(38°)
d) tan(52°)
Solution:
Let us use the trigonometric identities in the given .
We have to find the value of sin(38°).
We know that sine trigonometric identity is given as:
....... (1)
Now, let us find out the values of trigonometric functions given in options one by one:
....... (2)
By (1) and (2):
sin(38°) 
cos(38°).
...... (3)
Comparing equations (1) and (3):
we get the both are same.
11, count everything after 3 and everything before 4
Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%
Answer:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side. If you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. If that is not true, then it is not possible to construct a triangle with the given side lengths.
