Answer:
Step-by-step explanation:
we know that
----> by trigonometric identity
we have
substitute
Remember that
If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant
therefore
If the angle theta is on the I Quadrant the cosine will be positive
If the angle theta is on the II Quadrant the cosine will be negative
Answer: 258
Step-by-step explanation:
7/9 = 1800
2/9 = ?
= 258
A, C, and E
Any numbers that, when multiplied, produce the number 7.82 have the same value as 2.3 * 3.4. Some numbers include 2 * 3.91 and 17 * 0.46. A, C, and E, when simplified all equal 7.82
Answer:
Step-by-step explanation:
No it isn't because it wasn't an expression. An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)
