Solving for the angle on a right triangle, Cell Junctions and Protien Uses, Pearl Harbor,

To solve for the angle on a right triangle, you must use the correct trigonometric function for the respective sides of the triangle with the "-1" on it. Use a calculator to solve for the answer. The server won't let me upload the screenshot, unfortunately.

Cells have many junctions with many functions. After this sentence, I will tell you about five different substances that help cells in different ways. The extracellular matrix regulates the differation between cells. Cells walls are made of cellulose and maintains the shape of plant cells. Plasodesmotas allow usefull substances to be transported to nearby plant cells. Tight junctions act as a waterproof seal between cells. Desmosome junctions let tissues stretch without breaking. Cadherin protiens attach desmosomes together.

The attack of Pearl Harbor occured on December 7 in 1941, when the USS Nevada's band was conducting its daily rendition of "The Star-Spangled Banner". Near the end of the song, the Japanese attacked Pearl Harbor with 300 fighters. Attacking America's battleships with gunfire, torpedoes and bombs. All eight of the battleships were main targets and were destroyed. The USS Arizona was hit with the worst blasts, killing 1,000 people who were onboard the ship. It was one of the most suprising attacks to have hit America during WWII. The attack was so sudden that the most of the US Navy wasn't able to get to their posts in time. Japan also destroyed most of  the US's fighters before the pilots can get to them, allowing Japan to attack the US with ease.
