Answer:
A. 133
Step-by-step explanation:
Angle P is equal to the angle that is 133 because of the propertys of angles.
Answer:
C. 55
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we have:
40 + y + y + 30 = 180
2y + 70 = 180
2y = 110
y = 55
Answer:
Step-by-step explanation:One yard equals 0.9144 meter. Therefore 20 yards = 20 * 0.9144 = 18.288 meters
Answer:
3 - x
Step-by-step explanation:
f(x) = -x + 6
f(x + 3)
Substitute (x + 3) in for x;
f(x + 3) = -(x + 3) + 6
= - x - 3 + 6
= -x + 3
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.
