Answer:
237.9 meters
Step-by-step explanation:
Let x represent the length of the tunnel.
Applying the Cosine Law, we have:
x² = 201² + 146² - 2*201*146*Cos(85)
x² = 61,717 - 58,692*0.0872
x² = 61,717 - 5,117.9424
x² = 56,599.0576
x = √56,599.0576
x = 237.9 m (nearest tenth)
Answer:a
Step-by-step explanation:
Answer: Answer is in the steps
Step-by-step explanation:
The interior angles of a triangle add up to one 180 degrees so they all have to add up to 180 degrees.
A) (x+10)° + 50° + (x+20)° = 180°
B) Now solve for x using the equation
x+10 + 50 +x+20= 180
2x + 80 = 180
-80 -80
2x = 100
x = 50
Answer: (why is it 5 points?) Thats ok.
5 times what X is - 24 meaning whatever X is also by sry i don't make a lot of sense but i'm smart and know the answer. I will change it later after i find out which shouldn't take too long.

Thanks, stay safe, have a great life! Byes! Brainliest then i will give answer! ;) :) :P XD :3 (: hehe :)
