Answer:
I can only help with 5 and 6 which both are A.
Explanation:
that's because Cosine is adjacent to the angle (the angle being 30 degrees and the side next to it is 43mm) divided by the hypotenuse (longest side of a right triangle. The 50 mm). A way you can remember the sin, cosine and tangent is SOH CAH TOA. Sine=opposite over hypotenuse, Cosine = adjacent over hypotenuse, Tangent = opposite over adjacent. For the next one, it is the same principal. X is adjacent to 22 degrees and the other number is the hypotenuse so it has to be Cosine.
Answer: x= 10
Step-by-step explanation:
Answer:
m= -3
Step-by-step explanation:
slope intercept formula
(y2-y1)/ (x2-x1)
-6-3= -9
-2-1=-3
-9/3 =-3
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
