Answer:
∠A ≈ 72°
Step-by-step explanation:
Fill in the given numbers and do the arithmetic.
cos A = (2.9² +2.5² -3.2²)/(2(2.9)(2.5)) = 4.42/14.5
The inverse cosine function is used to find the angle, given its cosine.
A = arccos(4.42/14.5)
∠A ≈ 72°
The answer is c because S=Ph+2b
Answer: false.
Step-by-step explanation:
it's only a terminating decimal if you end up with a remainder of 0.
Compare the enumerators because they have the same denominator. 2 is large than 1 so 2/3 is larger than 1/3
Hope this helps!
