In △abc , m∠a=72° , m∠b=(8y−16)° , and m∠c=(9x)° . isosceles triangle abc. ab is the base, lateral sides ac and cb are marked congruent. what are x and y?

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.

This activity will you meet these educational goals: mathematical practices-you will make sense of problems and solve them, reason abstractly and quantitatively, and usemathematics to model real-world situations.directionsread the instructions for this self-checked activity type in your response to each question, and check your answers. at theend of the activity, write a brief evaluation of your work.
