Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 pe

pshichka [43]

Answer:

Step-by-step explanation:

Step one:

let us first compute the tuition and books for the two years

we are told that the tuition is $5,500 per year

For the two years,the tuition will be 5,500*2= $11,000

Step two:

we need to calculate the cost of transportation for the two years also

in two years there are 24 months

if Lakita will spend $100 per months

then in 24 months Lakita will spend= 24*100= $2400

Hence her education cost her in total is

=$11,000+$2400

=$13,400

Triangle F G E is shown. Angle F E G is a right angle. The length of hypotenuse F G is 18.6 inches and the length of F E is 12 i

Answer:

Measure of ∠FGE is 40.2°.

Step-by-step explanation:

Refer to the attachment.

Consider ΔFGE. Given that ∠FEG = 90° and ∠FGE is x°.

To find the value of ∠FGE use trigonometric ratios.

Use sine ratio to find the value of ∠FGE.

$\sin \theta=\dfrac{opposite\:side}{hypotenuse\:side}$

Rewriting it in terms of x° as follows,

$\sin x=\dfrac{opposite\:side}{hypotenuse\:side}$

Now find the opposite and hypotenuse side of the angle ∠FGE.

So opposite side of ∠FGE is FE and hypotenuse side of ∠FGE is FG.

Substituting the values,

$\sin x=\dfrac{FE}{FG}$

Given that length of FE is 12 inch and FG is 18.6 inch.

Substituting the value,

$\sin x=\dfrac{12}{18.6}$

To find the value of x, taking inverse sin.

$x=\arcsin \left(\dfrac{12}{18.6}\right)$

Calculating the value,

$x=40.17$

Rounding to nearest tenth the value of angle is 40.2

Therefore measure of ∠FGE is 40.2° .
