Answer:
a) 22°
Step-by-step explanation:
Side 'a' is the shortest side, so angle A will be the smallest angle. Its value must be less than 60°, eliminating the last two answer choices. The actual value can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (5² +7² -3²)/(2(5)(7)) = 65/70
A = arccos(65/70) ≈ 21.7868°
Angle A is about 22°.
P - 369 = 32 I believe but if you're supposed to use Division I would say, P / 369 = 32
The height in the scale drawing was 250 inches.
The answer is 3.814 but if you wanna round to the nearest hundredth then it’s 3.81
Answer:
Division means sharing an item equally. A fraction has two parts - a numerator and a denominator. ... Dividing fractions is almost the same as multiplying them. For the division of fractions, we multiply the first fraction by the reciprocal (inverse) of the second fraction.
