Find all missing angles of the 2 right triangles below. (The 10 cm belongs on the line from the peak to the base that separates the latge triangle into 2 right triangels)

Use the figure to the right to (a) identify the triangle as scalene, isosceles, or equilateral and as (b) acute, obtuse, or right. The parallel markings (the two small parallel lines) on two or more sides indicate that the marked sides are of equal length. (a) Is this triangle scalene, isosceles, or equilateral? O Equilateral C Scalene O Isosceles (b) Is this triangle acute, obtuse, or right? Acute O Right 000 Obtuse
