Answer:c
Step-by-step explanation:
Answer:
84.5
Step-by-step explanation:
Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.
Cos 77 = 19/x
0.22495 = 19/x
19/0.22495 = x
84.5 = x
Answer:
b. infinite solutions
Step-by-step explanation:
Therefore, the graphs are the same.
If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
Answer:
36.87°
Step-by-step explanation:
Since ABC is a right-angle triangle, we can use trigonometric ratios to solve for unknown angles and sides.
For Angle at A, we have lengths of opposite and adjacent sides so we can use tangent at A.
tan(A) = opposite/adjacent
tan(A) = CB/AB
tan(A) = 6/8
A = (tan^-1)(0.75)
A = 36.86989765°
