Answer: -2
Step-by-step explanation:
y-intercept: (0,5)
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.

Answer:
yes you're right :)
Step-by-step explanation:
you have to use the pythogram therom for this
a² + b² = c²
20² + 10² = c²
400 + 100 = c²
c = √500
