Find M<br> A. 17<br> B. 16<br> C. 18<br> D. 20
mixas84 [53]

Answer:

A. 17

Step-by-step explanation:

using the cosine rule (also see attached for reference):

AB² = BC² + AC² - 2·AC·BC cos C

2·AC·BC cos C = BC² + AC² - AB²

Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula

2(18)(28) cos C = 28² + 18² - 12²

1008 cos C = 964

cos C = 964/1008

cos C = 0.9563

C = cos⁻¹ 0.9563

C = 16.99 ( = 17° rounded to nearest degree)

What is a rational number between 7.7 and 7.9
Luda [366]
Hey mate ,

here is your answer

**********************

The average between any two rational numbers is also rational.
(7.7 + 7.9)/2 = 7.8
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal.
