Answer:
4y = 3
Step-by-step explanation:
To subtract the 2nd equation from the first, negate all three of the second equation terms: 3x + 2y = -4
and then add (combine) this result to (with) the first equation:
-3x + 2y = 7
3x +2y = -4
----------------------
4y = 3 (this is the desired result))
Answer:
About 50.92
Step-by-step explanation:
9514 1404 393
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°
