The most accurate "estimation" for 5+4 is um... 9
Answer:
The value of the given expression is 84.
Step-by-step explanation:
The given expression is
The number 252 can be written as 240+12, because 24 can easily divisible by 3.
The compatible numbers are 240 and 12
Therefore the value of the given expression is 84.
Answer: 25 km
Step-by-step explanation: 5 × 5 = 25
<u>Q1: Given sin(x+22)° = cos(2x−7)°
</u>
Using the concept of Right triangles and Trigonometric ratios, we can use a formula given as follows :-
If, sin(A) = cos(B). Then we must have A + B = 90 degrees.
We have sin(x+22)° = cos(2x−7)°
Then it must be true that (x+22)° + (2x−7)° = 90 degrees.
(x + 22) + (2x - 7) = 90
3x + 15 = 90
3x + 15 - 15 = 90 - 15
3x = 75
Hence, x = 25 degrees is the final answer.
<u>Q2: Given cos(x) = 1213 and sin(x) = 513. </u>
It says to find ratio of tan(x).
Using the concepts of Trigonometric ratios, We can the formula that relates all three functions i.e. sin(x), cos(x), and tan(x).
tan(x) =
We can plug the given values in the formula.
is the final answer.
1/4 =2/8+3/8 =5/8
1-5/8=3/8
