45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy
Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.

Answer:
the estimate of 145.5÷21 is 6.9 or 6. 93
Step-by-step explanation:
2L+2W=157.5
L=W-30
2(W-30)+2W=157.5
2W-60+2W=157.5
+60 +60
4w=217.5
W=54.4(.37 rounded to nearest tenth)
L=24.4
