In week 7 of math 10 we got introduced to trigonometry which is finding the missing side or sides or the angle of the right triangle you are solving, we learned ho to identify which sides are the HYPOTENUSE, ADJACENT, OPPOSITE (hypotenuse is across the right angle, the opposite is across from the angle and the adjacent is beside the angle)  We learned how to create equations from the numbers we are given. We learned SOH CAH TOA which helps us find which button to press on our calculator (sin, cos, tan)

In week 6 of math 10 we learned how to:

Find the surface area and volume of a sphere and hemisphere (half of a sphere).

SA=4 pi r^2

V=4/3 pi r^3

and for a hemisphere its 1/2 of a sphere + the SA of the cut part

we learned the SA and V for a cone and pyramid and how to convert the unites.

In week 5 in math 10 we learned how to find the volume and surface area of a rectangular prisms and cubes only based on knowing 2 measurements, we had to use the Pythagoras  theory.

adapted from the poem by Martin Niemmoler “first they came for the jews” in response to the poem “danger of silence”

First they came for the African Americans , and I did not speak out—
Because I was not an African American.

Then they came for the refugees, and I did not speak out—
Because I was not a refugee.

Then they came for the feminists, and I did not speak out—
Because I was not a feminist.

Then they came for me—                                                                                                                      and there was no one left to speak for me.
