Answer:
b =
Step-by-step explanation:
Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.
Thus, to determine the value of b;
Sin θ =
Sin b =
=
= 0.38462
⇒ b = 0.38462
= 22.6202
b =
The measure of angle E (= b) is .
=
1:4
since two halves of the given dimension (old area) is the new area ...which implies that the new area would be equivalent to 4 times the old area. i.e A = A'(1/4)
4A =A'
Answer:
For me people called it PEMDAS, Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
3.19 - 1.99 = 1.20 increase in 4 years
1.20/4 = 0.30
rate of change is 0.30 per year (30 cents per year)
Answer:
18/48 and 15/40
Step-by-step explanation:
18/48 = 3/8
15/40 = 3/8
•°• 18/48 is equivalent to 15/40
