On May 16, 2011, the space shuttle Endeavour launched for the last time. The total mass of the entire
spacecraft includes the Endeavour shuttle, its external rockets, its fuel tank, and its fuel. The total mass of
the entire spacecraft changed as fuel was used. The model below shows the predicted mass m, in
thousands of kilograms, of the entire spacecraft t seconds after the launch.
m = 2,050 - 9.75t, Osts 120
According to the given model, what was the predicted mass, in thousands of kilograms, of the entire
spacecraft 60 seconds after launch?

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
