Answer:
z=1
Step-by-step explanation:
3z+(-4)=-1
Add 4 to each side
3z+(-4) +4=-1+4
3z = 3
Divide each side by 3
3z/3 = 3/3
z=1
So the definition of the cosine of an angle of a right triangle is

. You may remember this by SohCahToa (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent).
Remember, adjacent refers to the side next to the angle in question, and the side can't also be the hypotenuse. The hypotenuse is that longest side and is opposite the right angle.
We have the cosine of 30°. We write
Answer:
9,375
Step-by-step explanation:
Each number is multiplied by 5 to get the next number. We can see this by testing multiple number on this set of data.
3*5=15
15*5=75
75*5=375.
Thus, to find the next term in the set of data, we must multiply the last number that we are given by 5.
1875*5=9,375
The next number is 9,375
Hope this helps!
The number may be 6 because 6 • 3 = 18, and 2 more than 18 would be 20
I’m not sure but i hope you get it correct : )
