Answer:
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
17 is the total inches
17/2 is 8.5 multiplied by 3 is 25.5 miles which convert to 26
so the answer is C!
hope I helped!
The answer is 18 I believe.
Answer:
A. The temperatures of the iron bars after 30 minutes would be less than 160°C because heat would be lost to the surroundings.
Step-by-step explanation:
The hotter bar would lose heat to both the cooler bar and the surroundings. The cooler bar would gain heat from the hotter bar, but lose heat to the surroundings. Because heat is lost to the surroundings, the temperature of the iron will be less at the same time (after 30 minutes) than it would be in an isolated system.
90 degrees is 1/4 of the circle ( 90 * 4 = 360 degrees = full circle).
Divide the area of the circle by 4:
314 / 4 = 78.5 square inches is shaded.
