In a geometric diagram, <A and <B are complementary, and they form a straight line with <C. If m<A = x°, m<B = (2x) °, and m<C = 90*, what is the measure of <B?
(1 point)
If <A and <B are complementary, it means that <A + <B = 90°.
Given that m<A = x° and m<B = (2x)°, we have:
x + 2x = 90
3x = 90
x = 30
Therefore, the measure of <B is:
2(30) = 60°.
