Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
All fractions that are less than 1/2 but more than 0.
The inequality is 0>1/2
Answer:
180
Step-by-step explanation:
It's 180 because 75% of 240 is 180.
Answer:
y = -53/2, x = -17
Step-by-step explanation:
1/2x + 3/2 = -7
-3x +2y = -2
Isolate X for 1/2x + 3/2 = -7
X = -17
Substitute X = -17
-3(-17) + 2y = -2
Isolate Y for -3 (-17) + 2y = -2
Y = -53/2
They give you: <RSP = 90 degrees
If you look in the diagram, <RSP is vertical to <UPW and vertical angles have the same measure. <RSP = <UPW
So the correct answer is A.
