Step-by-step explanation:

Bir abzas qurmaq üçün 5 addımdan keçək. Hər addım üçün bir izah və nümunə var. Nümunə bəndimiz kölə ruhları haqqında, Afrikalı Amerikalıların köləlik dövründə yaratdığı orijinal mahnılarla əlaqəli olacaq. Model paraqrafı fikrini sübut etmək üçün illüstrasiyadan (nümunələr verməklə) istifadə edir.

Geometry - Law of Sines question #17. Please help, I am stuck.
Flauer [41]

By the law of sines, m∠<em>EFG</em> is such that

sin(m∠<em>EFG</em>) / (8 in.) = sin(m∠<em>G</em>) / (7.5 in)

so you need to find m∠<em>G</em>.

The interior angles to any triangle sum to 180°, so

m∠<em>DEG</em> = m∠<em>D</em> + m∠<em>G</em> + 43°

m∠<em>DEG</em> + m∠<em>D</em> + m∠<em>G </em>= 2 (m∠<em>D</em> + m∠<em>G</em>) + 43°

180° = 2 (m∠<em>D</em> + m∠<em>G</em>) + 43°

137° = 2 (m∠<em>D</em> + m∠<em>G</em>)

68.5° = m∠<em>D</em> + m∠<em>G</em>

But ∆<em>DEG</em> is isosceles, so m∠<em>D</em> = m∠<em>G</em>, which means

68.5° = 2 m∠<em>G</em>

34.25° = m∠<em>G</em>

<em />

Then

sin(m∠<em>EFG</em>) = (8 in.) sin(34.25°) / (7.5 in)

m∠<em>EFG</em> ≈ sin⁻¹(0.600325) ≈ 36.8932°
