Answer:
Option D
Step-by-step explanation:
By applying cosine rule in the given triangle,
a² = b² + c² - 2b.c.cos(m∠A)
By substituting values in the formula,
9² = 10² + c² - 2(10)(c)cos(15)°
81 = 100 + c² - 19.32c
c² - 19.31c + 19 = 0
By quadratic formula,
c =
=
= 1.08, 18.27
≈ 1.1, 18.3
Therefore, Option D will be the answer.
How many times does 24 go into 7?
7 × 1 = 7
7 × 2 = 14
7 × 3 = 21
7 × 4 = 28
7 goes into 24 only three times, leaving three remainder. So you would write it like this: 3
. 7 goes into 24 three times, there is three left over as remainder, and the denominator from before is 7. Thus the answer.
I do hope this helped :))
