Please help me asappp (will give brainiest!)

Answer:

TanФ=-1.793

Step-by-step explanation:

$Sin^{2} (A) + Cos^{2} (A) = 1$

$Sin(A)=\sqrt{1-Cos^{2} (A)}$

$Tan(A) = \frac{Sin(A)}{Cos(A)}$

$Tan(A) =\frac{\sqrt{1-Cos^{2}(A) } }{Cos(A)} \\Tan(A) =\frac{\sqrt{1-(-.487)^{2} } }{-.487}=-1.793433202$

Anyone know the answer ???

Hello!

Since the angles are same side alternate angles they are equal to each other

60 - 2x = 70 - 4x

We solve this algebraically

Add 4x to both sides

60 + 2x = 70

Subtract 60 from both sides

2x = 10

divide both sides by 2

x = 5

Hope this helps!
