A triangle has 3 interior angles and the sum of its interior angles is 180°. If one of the three interior angles measures 80° and the two remaining angles has the same measure, what is the measure of the 3rd interior angle?

The 3 rd interior angle would have the measure of 50°as the question says that the remaining two interior angles have the congruent magnitude thats why if one of the interior angle is 80° then the remaining angles would be 100° So as the remaining two angles measure the same we can say that the third angle measures 100°/2 = 50°

For proof :

If the remaining two angles be x then the equation forms

x + x + 80° = 180°

=> 2x = (180 - 80)°

=> x = (100/2)°

=> x = 50°

Therefore the value of x = 50°

Hope it helps

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
