The basic unit of length in the metric system is meter.
Keep trying at this question, I believe in you! Here's the answer just in case. :)
Answer: 0.83644865915
Nearest hundredth would be 0.84.
I can explain it if you'd like.
Edit: Here's how I did it just in case anybody wants to know :) Not that anybody wants to know but just in case because you never know! :)
SOH CAH TOA
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
So the cosine of W would be 65(the adjacent side)/97(the hypotenuse)
Because you don't know what W equals, you'd use a calculator and click the little 2nd button, then click the cos button. And then you'd type in the 65/97 and hit the equals button and that's the answer!
If I'm incorrect I guess tell me somehow? Alright, have a great day/night! ^-^
Answer:
The answer to your question is: ∠4 = 140°
Step-by-step explanation:
If there are two parallel lines cut by a transversal line 8 angles are formed.
These angles are classified as corresponding angles, alternate exterior angles, alternate interior angles and same-side angles.
Alternate exterior angles measure the same. Also alternate interior angles measure the same.
Same-side angles are supplementary angles, that means that their sum gives 180°.
Finally corresponding angles measure the same.
In the figure we notice that angles 6 and 8 are same side angles, so:
∠6 + ∠8 = 180
and ∠6 = 40° 40 + ∠8 = 180
∠8 = 180 - 40
∠8 = 140°
and ∠4 and ∠8 are corresponding angles so,
∠4 = ∠8 = 140°
