Answer:
d
Step-by-step explanation:
the reasoning for this is because you count all the 2's and the little number in the corner and then you can't leave the 7 so you put the x7 for that reason
When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.
8 = 3/4 w Divide by 3/4
w = 8/(3/4)
w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.
w = (8 x 4) / 3
w = 32 / 3
w = 10 2/3

Answer:

Step-by-step explanation:
step 1
Find the 
we know that
Applying the trigonometric identity

we have

substitute





Remember that
π≤θ≤3π/2
so
Angle θ belong to the III Quadrant
That means ----> The sin(θ) is negative

step 2
Find the sec(β)
Applying the trigonometric identity

we have

substitute




we know
0≤β≤π/2 ----> II Quadrant
so
sec(β), sin(β) and cos(β) are positive

Remember that

therefore

step 3
Find the sin(β)
we know that

we have


substitute

therefore

step 4
Find sin(θ+β)
we know that

so
In this problem

we have




substitute the given values in the formula
