Step-by-step explanation:
so...the answer is C.27.7m
angle1 = 4y - 9°
angle2 = 40°
angle3 = 5y°
Angle sum property
180° = angle1 + angle2 + angle3
Therefore,
180 = (4y - 9) + 40 + 5y
180 = 4y - 9 + 40 + 5y
180 = 9y + 31
180 - 31 = 9y
149 = 9y
149/9 = y
Factorization
completing square
quadratic formula
the answer would be, "The width is" all of the other information is neccesary!! You could not solve the problem without knowing what the the toal is and what the length is!! You need that info. So "the width is" is not important cuz if you were to take 24 and divide it by 3 * 2 you would have the width.
Hello.
Numbers with | | around them are the absolute value, meaning it is always positive.
|-1.43| and |-1.21| become 1.43 and 1.21
The equation is now 1.43 - 7.1 + 1.21
Solve.
1.43 - 7.1 + 1.21
-5.67 + 1.21
-4.46
-4.46 is the final answer.
