Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x
60 + 2x = 70
2x = 10
x= 5
We will use tangent here as we are finding the opposite with the adjacent given.
So we can simply just put this into a calculator:
tan(68°) × 7 cm = AC
tan(68°) × 7 cm = 17.3 cm
Answer:
the answer should be 4x
Step-by-step explanation:
i apoligize if i'm wrong
It is 255 cm^2
This is a very basic area problem. You should try refreshing on some of your multiplication and addition skills. Try reading patterns, maybe. Also learning geometric proofs is VITAL.
