Find the value of X round to the nearest 10th law of cosines.
1 answer:
Image of triangle is missing, so i have attached it.
Answer:
x = 18
Step-by-step explanation:
From the diagram attached, we can see that the 3 given sides have dimensions of x, 16 and 30.
Also, we see the angle opposite the dimension of x is 30°
Thus,we can use law of cosine to fjnd the value of x. Thus:
x² = 16² + 30² - 2(16 × 30)cos 30
x² = 256 + 900 - (960 × 0.866)
x² = 324.64
x = √324.64
x = 18.02
Approximating to the nearest tenth gives; x = 18

Solution :
Modular math is defined as
or
Where, A is the dividend
B is the divisor
Q is the quotient
R is the remainder
The solution is
Now, We perform same in every case
1)
We can direct add the term,
Now, we divide 15 by 5 and see the remainder
Remainder is 0.
So,
2)
We can direct subtract the term,
Now, we divide -4 by 12 and see the remainder
Remainder is 8.
So,
3)
We can direct multiply the term,
Now, we divide 12 by 5 and see the remainder
Remainder is 2.
So,
4)
We can direct divide the term,
Now, we divide 0.5 by 5 and see the remainder
Remainder is 0.5.
So,
