Let <A , <B , and <C be acute angles. Use a calculator to approximate the measures of <A , <B , and <C to the nearest tenth of a degree. cos A = 0.31 , sin B = 0.89 , tan C = 0.52

m<A =
m<B =
m<C =​

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.
