Asking again. Please answer!!! What is the measure of Lx?
Angles are not necessarily drawn to scale.

∠x = 75°

Step-by-step explanation:

     We know that a triangle's angles add up to 180°. See the triangle I have highlighted in the attachment. We know two of the angles for this triangle, so we can find the 3rd.

     180° - 36° - 39° = 105°

     Now, since a line is equal to 180°, we can find ∠x to answer our question.

     180° - 105° = 75°

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales
