By the Pythagorean theorem, the missing side is -sqrt7. The definition of sin is side opposite over hypotenuse, so go into Q2 and make an angle and label the side opposite the angle with a 3 and the hypotenuse a 4. The other leg is -sqrt7 cuz x is negative in Q2. The cosine of an angle is the side adjacent over the hypotenuse, so the cos then is -sqrt7/4

Answer:
14. C) 136°
15. C) 40°
Step-by-step explanation:
Inscribed angles are half the measure of the arc they intercept. For an inscribed quadrilateral, this means opposite angles are supplementary.
__
14) ∠H +∠W = 180°
34x +55x +2 = 180
89x = 178 . . . . . . . . . subtract 2
x = 2 . . . . . . . . . . . . . divide by 89
arc VX = 2(34x) = 68(2) = 136 . . . degrees
__
15) The sum of angles in the triangle is 180°.
? + 80° + (120°/2) = 180°
? = 40° . . . . . . . . . . subtract 140°

Answer:
About 163 388 employees
Step-by-step explanation:
Let total number of employees in the company be represented by x. Thus:
Divide through by 0.183
The total number of employees in one country is about 163388
The ratio of the areas will be:
<span><span>192 / 363</span>=<span>64/ 121
</span></span>
The ratio of the sides will be the square root of that:
<span><span><span>sqrt(</span><span>64/121</span>)=<span>811</span></span></span>
