Answer:
Step-by-step explanation:
the diameter of this circle is 7.4 km
the radius of this circle is 7.4 km/2=3.7 km
second choice
180°. The answer is 180° because it is a straight line rather than being curved/bent.
Step-by-step explanation:
3. The triangle that makes up the square is a 45-90-45 triangle so x = 45°. Using Pythagorean theorem,
2y^2 = 12 ---> y^2 = 6
or
y = √6
4.This is an equilateral triangle of side 11 so
y = 11/2
To find x, use the definition of sine 60:
sin 60° = opp/hyp
= x/11
or
x = 11sin60° = (11√3)/2
Two yards is equal to six feet, one yard is 3 feet
