c^2 = a^2 + b^2 - 2*ab*Cos(C)

c = 16; a = 17; b = 8 (what you call a and b don't really matter. c does). Substitute.

16^2 = 17^2 + 8^2 - 2*17*8*Cos(C) Add the first 2 on the right.

256 = 289 + 64 - 282*cos(C)

256 = 353 - 282*cos(C) Whatever you do, don't do any more combing on the right side. Subtract 353 from both sides.

-97 = -282 * cos(C ) Divide by 282

0.34397 = cos(C)

cos-1(0.34397) = C ; C = 69.88 degrees.


Do you need more help on this question? All of these are done the same way.

Given: BC = AD, AD = 17 DC = 14, m∠1=m∠2 Find: AB, BC
Mariulka [41]

Answer:

AB = 14 and BC = 17

Step-by-step explanation:

Congruence is a property that shows an equal relation between sides or angles of a given figure or two figures.

From the question, the given conditions are;

BC = AD, AD = 17, DC = 14, and m< 1 = m<2 .

i. Considering the property of congruence of sides,

BC = 17 (∵ BC = AD and AD has been given to equal 17)

i.e BC = AD = 17

ii. Considering the property of congruent angles and sides,

AB = 14 (∵ m<1 = m<2 and DC is 14)

Therefore, AB = 14 and BC = 17.
