The Correct choice is <u>Substition method</u> , as we can directly substitute the value of y from first equation to the second equation.
Answer:
186.3
Step-by-step explanation:
9514 1404 393
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°
1 + 1 + 1 + 2 = 5
5 x 9 = 45
Therefore, the total number of km is 45.
