Hello!
To find our answer, we just use a scientific calculator (you cannot calculate it by hand).
tan42≈0.9
Therefore, our answer is about 0.9.
I hope this helps!
Let width be x
Length would be x + 3
Area = L * W
Make an equation
(x) * (x+3) = 70
x^2 + 3x = 70
x^2 + 3x - 70 = 0
Quadratic formula
(-3 +/- rt 3^2 - 4 * 1 * (-70))/(2 * 1)
x1 = (-3 + 17)/2, x2 = (-3-17)/2
x = 7, x = -10
Dimension cannot be negative
Solution: width = 7
Length = 10
1/6 is greater than 1/8, because when you change the fractions 1/6 will be 4/24 but 1/8 will be 3/24. To change the fractions you first have to find the lowest number that both denominators can go in, so it is 24. 6 can go into 24 four times, so you multiply the numerator by 4 making 1/6 4/24. 8 can go into 24 three times, so you multiply the numerator by 3 so 1/8 = 3/24.
Answer:
x=65
Step-by-step explanation:
solve for the angle not marked⇒ 180-147=33
add known angles⇒ 33+82= 115
subtract total known value from 180**⇒ 180-115=65
**all interior angles of a triangle must add up to 180°
Given P is T, q is F and r is F.
Let us find p ↔ q first.
↔ is called bi-conditional operator and is true when p and q both are matched.
Since here p is T and q is F, p↔q is F. ( Since p and q are not matching)
~p v r = ~T v F = F v F = F
Hence (p↔q)→(~pvr) = F → F = T (Since conditional operator → is false if and if first proposition is T and second proposition is F, for all other values it is T)
