Answer:
1 and 9/28
Step-by-step explanation:
you need to put everything over the same denominator
21/28+16/28=37/28
this can be written as 1 9/28
Answer:
99.5 minutes
Step-by-step explanation:
50=45
495=?
495×45÷50=99.5
Your missing angle will be 73 degrees, because the angles all add up to 180. So you add 33 and 74 then subtract that from 180
This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;
Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;
The side length will be 8 units since the y-coordinate is -8
The side width will be 3 units since the x- coordinate is 3
c^2=a^2+b^2
c^2=(3)^2+(-8)^2
c^2=9+64
c^2=73
c=sqrt(73)
Therefore the sine value will be:
sin x=3/sqrt(73)
multiply both numerator and denominator by sqrt(73) we get:
sin x=(3√73)/73
Therefore the answer is A]
