Answer:
a=−b−c−d+15
Step-by-step explanation:
Step 1: Add -b to both sides.
a+b+c+d+−b=15+−b
a+c+d=−b+15
Step 2: Add -c to both sides.
a+c+d+−c=−b+15+−c
a+d=−b−c+15Step 3: Add -d to both sides.
a+d+−d=−b−c+15+−d
a=−b−c−d+15
Sin 0 = 0
Sin 30 = 1/2
Sin 45 = 1/SR of 2
Sin 60 = SR of 3/2
Sin 90 = 1
Answer:
E
Step-by-step explanation:
In the picture attached, the Truth Table for the operator “OR” is shown. With it we can compute the next table:
p q ∧ r p ∨ (q ∧ r)
T T T
T F T
F T T
F F F
We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.
The only row from the table of the question that satisfies this criterion is row E.
Answer:
x=-7
Step-by-step explanation:
5-x=3(x+11)
Distribute 3 to the parenthesis. (Multiply)
5-x=3x+33
Subtract 33 from both sides.
-28-x=3x
Add x to both sides,
-28=4x
Divide both sides by 4.
-7=x
Answer:
∠ f = 33°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin f =
=
, thus
∠ f =
(
) = 33° ( to the nearest degree )
