Answer:
Step-by-step explanation:
7a + 7c = 861 ...... <em>(1)</em>
7a + 5c = 829 ..... <em>(2)</em>
<em>(1)</em> - <em>(2)</em>
2c = 32
<u><em>c = 16</em></u>
<u><em>a = </em></u>123 - 16 =<u><em> 107</em></u>
So it can now be bought for 65% of its regular price.
That's a good deal. If I needed a clearance rack, I'd buy it.

Answer:
71°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠H = 180° -109° = 71°
_____
<em>Additional comment</em>
The above rule comes from the more general rule that the measure of an inscribed angle is half the measure of the arc it intercepts. Here, inscribed angle J intercepts arc GHI, so that arc has measure 2×109°. Then the measure of short arc GI is 360° -2×109°, and inscribed angle H is half that:
∠H = (1/2)(360° -2×109°)
∠H = 180° -109° = 71°
