Answer:
As shown in picture:
Original x = 360 - (59 + 108 + 81) = 112 deg
Upper bound of x (when all known elements are considered at lower bound)
U = 360 - (58 + 107 + 80) = 115 deg
Lower bound of x (when all known elements are considered at upper bound)
L = 360 - (60 + 109 + 82) = 109 deg
Hope this helps!

Neither, it is not going straight up or straight right.
Answer:
x=1.5
Step-by-step explanation:
triangle JLM is similar to triangle QST
so we know that similar triangles have proportionate sides
so..
JM/LM=QT/ST
4/(6x-3)=2/3
3*4=2(6x-3)
12=12x-6
12x=18
x=1.5
Answer:
B)y = 3x^2 - 3x-18
Step-by-step explanation:
y = (3x – 9)(x + 2)
y = 3x*x+3x*2-9*x-9*2
y = 3x^2 +6x-9x-18
y = 3x^2 - 3x-18
Answer:
Total revenue by the toll bridge = $45
Step-by-step explanation:
Total vehicles crosses the bridge = 30
Number of passenger cars = 60 % of all vehicles = = 18
Other vehicles = 30 - 18 = 12
Charges for one passenger cars = $1.00
Thus total Revenue by the passenger cars = 18 × 1 = $18
Charges for other vehicles = $2.25
Total revenue by other vehicles = 2.25 × 12 = $27
Thus the total revenue from the toll bridge = 18 + 27 = $45
