I'm going for a range of 0 < x <2<span>π
This is R sin (x-a), although R is 1.
a = </span><span>π/7, so
=> sin (x-(</span><span>π/7)) = -1/(sqrt(2))
=> x = 53</span>π/28, 39<span>π/28</span>
Answer:
All Negative numbers are NOT integers
Step-by-step explanation:
For example, If we take the negative number, -5/6
It is NOT a integer, it is a rational number.
Thus, this statement is wrong.
Answer:
18.0
Step-by-step explanation:
==>Given:
Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°
==>Required:
Value of x to the nearest tenth
==>Solution:
Using the Cosine rule: c² = a² + b² - 2abcos(C)
Let c = x,
a = 16
b = 30
C = 30°
Thus,
c² = 16² + 30² - 2*16*30*cos 30°
c² = 256 + 900 - 960 * 0.8660
c² = 1,156 - 831.36
c² = 324.64
c = √324.64
c = 18.017769
x ≈ 18.0 (rounded to nearest tenth)
30 is the answer
15% of 200 is 30 meaning he has 30 twin cards
