How do i state if each triangle is acut, obtuse, or right using the pythagorean theorem?

An acute angle is smaller than the right angle which means less than 90 degrees obtuse is more than 90 degrees but less than 180 degrees and a right angle is the biggest which is 180 degrees and you can fit a tiny square in the inside

You would plot 83 on the 83 line and you would plot -113 on the -113 line.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
