PRACTICE EXERCISES: Solve the following problems by completing the statements. One way to build stairs is to attach triangular blocks to an angled support, as shown. The sides of the angled support are parallel. If the support makes an angle of 32° with the floor, what must m/1 be so the top of the step will be parallel to the floor? triangular block 32 Solution: m/2 =_____(1)_ because they are _(2)_ But m/1 angles and are congruent. m/ (3) since they are alternate _angles. So, m/1 must be ___(5)______ _(4)_ A. The diagram shows that CF // _(6)_with AL and_ (7)____as the transversals. Angle BEF is__(8)____to/EHJ since they are _(9)__angles. On the other side, /EDH and /DHJ are consecutive (10)_angles, hence, they are (11)_ The vertical angles are /KHL and_ (12)_. So, m/DHE (13) Therefore, the equation is: (x +39) +(14)= 180 and x = (15) B Fig.2 DV76 E H G HD 39​
