The right answer is the first option: Churchill's famous speech convinced many Americans that the USSR was an enemy rather than an ally, which led to the creation of the Truman Doctrine.

The Truman Doctrine itself was an American foreign policy made to counter the USSR's geopolitcal sphere of influence to spread. Churchill used the term "Iron Curtain" to refer to the threat the Soviet Union presented to the rest of Europe.  

The way that Winston Churchill's "Iron Curtain" speech impacted the Truman Doctrine was A. Churchill’s famous speech convinced many Americans that the USSR was an enemy rather than an ally, which led to the creation of the Truman Doctrine.

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°
