Check the picture below
I'm thinking is the blue one, since it's less than π, and supplementary angles add up to π
Answer:
Part 1)
Part 2)
Part 3) and
Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
Find the side b
we know that
In the right triangle ABC
The function sine of angle B is equal to divide the opposite side angle B (AC) by the hypotenuse (AB)
we have
substitute
solve for b
step 2
Find the side a
we know that
In the right triangle ABC
The function cosine of angle B is equal to divide the adjacent side angle B (BC) by the hypotenuse (AB)
we have
substitute
solve for a
step 3
Find the measure of angle A
we know that
In the right triangle ABC
----> is a right angle
∠A+∠B=90° ------> by complementary angles
substitute the given value
Each time you roll a die there is a chance out of 6 because there are 6 faces. Therefore because you rolled it 6 times
6 x 6 = 36
So it's out of 36
3 even numbers on a die
3 x 6 = 18
Your answer is:
18/36
Which can be simplified to:
1/2
They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
<span>5x3 − 6x4
</span>So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you : )
