Question

Someone help me and explain . this is confusing.

Answer 1

Answer: 5) ∠E = 75°, ∠R = 15°, ∠W = 90°

               6) An obtuse angle is greater than 90°. If there were 2 angles greater than 90°, then it could not be a triangle because the three angles would be greater than 180° and a triangle has three angles whose sum is 180°

              7a) KH, b)KC & CH, c) ∠C, d) ∠K

Step-by-step explanation:

Since ER is the hypotenuse, then ∠W is the right angle ⇒ ∠W = 90°

 E                         ∠E = 5∠R

 |\                                                  ∠E  + ∠R = 90°

 |  \                                               5∠R + ∠R = 90°

 |    \                                                      6∠R = 90°

 |      \                                                      ∠R = 15°

 |         \

W           R              ∠E = 5∠R

                                   = 5(15°)

                                   = 75°          

*******************************************************************************

Since CK is perpendicular to CH, then ∠C is a right angle ⇒ ∠C = 90°

 K                        

 |\          a) the hypotenuse is KH        

 |  \        b) the legs are the perpendicular line segments (CK & CH)

 |    \      c)  see comment above (∠C = 90°)                                      

 |      \    d) ∠K + ∠H = 90°, therefore they are complimentary  ∠s

 |         \

C          H
