Question

The flag of a country contains an isosceles triangle.​ (Recall that an isosceles triangle contains two angles with the same​ measure.) If the measure of the third angle of the triangle is 45​° more than three times nbsp the measure of either of the other two​ angles, find the measure of each angle of the triangle.​ (Recall that the sum of the measures of the angles of a triangle is​ 180°.)

Answer 1

the angles sum to 180​°, so if the two equal angles are x​°, we have
2x + (3x+45) = 180
Find x, then use that to give the angles.

Answer 2

x = 27 lol

Answer 3

the first angle is 27​°, the second angle is 27°, and the third angle is 126​°.

Answer 4

The left and right page numbers of an open book are two consecutive integers whose sum is 399   Find these page numbers.
