Answer:
AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm
-11x-13+(7x-14)
-4x-27
B
(Mark me brainliest!)
The two plans don't fall directly on a same prive, but after 3 hours of Data usage plan B costs more than plan A
After three hours plan A= $18.60
While plan B after three hours =$19.09
That means 3 hours has to pass before plan B costs more, That is 180 minutes
The rule per hour is $1.2 per hour for plan A and $4.8 per hour for plan B
1) Vertical angles-the angles will equal each other.
8+7x=9x-4
12+7x=9x
12=2x
x=6
2) Supplementary-Angles will add up to 180
6+13x+7x+14=180
20+20x=180
20x=160
x=8
