Number 11, use law of sine
sin115/49=sinx/16
sinx=(sin115*16)/49)
sinx=0.3087
use your calculator: x is about 18 degree
question 12
two sides and the angle between them are given, use law of consine:
x²=14²+10²-2*14*10cos44
x is about 9.7
Probability (P) is basically outcome, and chance. What are the chances of grabbing a red or blue marble?
Well, there IS a more complicated way to solve this, but let's go the easy way.
You calculate probability with this equation:
Probability=Events/Number of outcomes
If you want to find the probability of grabbing a red or blue marble, you first have to find all possible outcomes by adding ALL numbers together. 6+6+4=16. Next, find how many events you have. Well, you want to find red or blue. Add the number of red and blue marbles together. 6+4=10, so your equation now looks like: Probability=10/16
Now, just simplify.
10/16 can be divided evenly by 2 on both sides, so just do that, and you get:
5/8
You have a 5/8 chance, or a 0.625 chance of drawing a red or blue marble.

Answer:
gradient =
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
4y - 5x = 2 ( add 5x to both sides )
4y = 5x + 2 ( divide the terms by 4 )
y = x + ← in slope- intercept form
with gradient m =
