Question

Find the vaule of x. then classify each triangle as acute, right, or obtuse

Answer 1

Answer:

1.) x = 90 (Right angle)

2.) x = 103 (Obtuse angle)

Step-by-step explanation:

• All triangles' angles have a sum of 180°.
• <90° = Acute, 90° = Right, >90° = Obtuse

$1.)\\x+48+42=180\\x+90=180\\x=90\\\\2.)\\x+45+32=180\\x+77=180\\x=103$

Answer 2

Answer:

1) = 90=acute angle   2)103=acute angle
