Using the law of cosines, a=2.2
Shkiper50 [21]
Answer: 81°


Explanation:


1) Law of cosines:


In a triangle with sides a, b, c whose opposite angles are, respectively, A, B and C, the law of cosines states:


b² = a² + c² - 2 (a)(c) cos (B)


2) In the triangle of the figure you have


b = 4.0
B = ?
a = 2.2
c = 3.7

⇒ (4.0)² = (2.2)² + (3.7)² - 2 (2.2) (3.7) cos(B)

⇒ 16 = 4.84 + 13.69 - 16.28cos(B)

⇒ 16.28 cos(B) = 4.84 + 13.69 - 16 = 2.53

⇒ cos(B) = 2.53 / 16.28

⇒ X = arccos(2.53 / 16.28 ) = 81.06° ≈ 81°

PLEASE HELP !!!!!<br>Solve.<br>y +30 &lt; 15<br><br>​
Troyanec [42]

Hello there! y < -15

To solve, isolate y. To do this, subtract 30 from both sides of the equation.

y + 30-30 < 15-30

y < -15

This is your final answer. The statement is saying that y must be less than -15 when you add 30 to it for your final answer to be less than 15.

I hope this was helpful and have a great rest of your day! :)
