Hello.

e is a mathematical constant, and it's like pi, it's irrational. It's approximately equal to 2.71828....

So, $e^{\frac{3}{2}} = 4.4816...$
It's approximately equal to 4.5 which is choice 2.

Answer:

Q3. 12 units
Q4. 6.33 units
Q5. 66.19°

Step-by-step explanation:

DE and DF are legs and EF is hypotenuse

DE = √EF² - DF²
DE = √13² - 5² = √169 - 25 = √ 144 = 12
DE = 12 units

PR is opposite side of angle Q and RQ is adjacent side

tan 54 = PR/RQ
tan 54 = PR / 4.6
PR = 4.6tan 54
PR = 6.33 units

As previous question, using tan as BC is opposite and AC is adjacent leg of angle A

tan A = 6.8/3
tan A = 2.266
A = arctan (2.266)
A = 66.19°
