Answer:
54.5
Step-by-step explanation:
divide it to one rectangle and two different triangles.
Rectangles area: (8+3)*4 = 44
triangle top: 4*3/2 = 6
triangle bottom: 3*3/2= 4.5
sum the all up: 44+6+4.5 = 54.5
don't know how to do it with π though if that's obligatory
Answer:
D.) 8:00
It’s a geometric problem so when plugged in you get answer D
Count change of signs to tell positive roots
then replace x with -x and evaluate, then count change in sign for negative roots
initially
+, -, -, +, +, -
3 changes
3 or 1 positive roots
replacing x with -x
-,-,+,+,-,-
2 changes
2 or 0 negative roots
B is answer
Step-by-step explanation:
Let x represent theta.
Using the angle addition trig formula,
Multiply one side at a time
Replace theta with x , the answer is
2. Convert 30 degrees into radian
Using tangent formula,
Tan if pi/6 is sqr root of 3/3
Since my phone about to die if you later simplify that,
you'll get
Replace theta with X.
