Ugh, more algebra pretending to be geometry. Why?
This is a pretty awful instance of the genre, with no units on the constant 16, assumed to be degrees.
The total arc measure in a circle is 360 degrees. Geometry part over.
3m + 16 + 2m + 3m = 360
8m = 344
m = 344/8 = 43
Arc measures:
Arc 3m+16 = 3(43)+16 = 145°. The angle subtended by that arc is half that, 145/2=72.5°
Arc 2m=2(43)=86°. The angle subtended is half that, 43°
Arc 3m=3(43)=129°. The angle subtended is half that, 64.5°
Each tank holds 4.25 gallons! 17/4 is 4.25 :) hope this helps!
Her statue is 20cm because 5ftx12cm is 60ft. therefore the statue should be 60ft in total. 60÷4=20 therefore her drawing is 20cm tall.
Answer: 540
Step-by-step explanation:
To solve this expression, we use PEMDAS to solve it.
-9*-6= 54
54*10=540
180 - 143 = 37
180 - 37 - 61 = 82
The answer is 82°
