On a piece of paper, use a protractor to construct right triangle ABC with BC=5 cm, m∠B=60°, and m∠C=90°. Which statement is true about this triangle?

AC=5 cm

AB=5 cm

AC=10 cm

AB=10 cm

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the correct position in the answer box. release your mouse button when the item is place. if you change your mind, drag the item to the trashcan. click the trashcan to clear all your answers. using the technique in the model above, find the missing segments in this 30°-60°-90° right triangle. ab = 8 bc = 4 cd =

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36
