A triangle has an angle that measures 55°. The other two angles are in a ratio of 11:14. What are the measures of those two angles?
the sum of the internal angles of a triangle is 180 °, we take 55 ° of the known angle and we have the sum of the other two, 125 °, the ratio is 11:14, one is 11 units and one is 14 units, we add them and we divide 125 ° by (11 + 14) = 25 and we have a unit, 125: 25 = 5. now we multiply the unit first by 11 and then by 14 and find the measure of the angles.
11 * 5 = 55°
14 * 5 = 70°
--------------------
check
55 + 55 + 70 = 180°
the sum of the interior angles of a triangle is 180,
The slope would be -1 or -1/1. They are both the same thing.
The slope is the number which is located directly to the left of the variable (the variable in this case is x, but in other situations it could be a totally different letter).
