Answer:
(B) 26°
Step-by-step explanation:
The angle at A made by the radius and the tangent is 90°. The angle at O is the same as arc AB, 64°. The acute angles in a right triangle are complementary, so the angle at C is the complement of 64°.
∠ACB = 90° -64°
∠ACB = 26°
f(x)=xy3 -4xy2 -7x+10
the xy3 and xy2 means x to the 3rd power and x to the second power
it's G)
I think the answer is letter A.
