Answer 1

Answer:

a).

in quadrilateral STUR ,

<T = 110°

< U = 70°

b).

Y = 215°

Step-by-step explanation:

a).

in quadrilateral STUR ,

<S + < T + < U + < R = 360°

70° + ( 23x - 5 ) + 14x + 110° = 360°

70° + 110° - 5 ° + 23x + 14x = 360°

175° + 37x = 360°

37x = 360° - 175°

37x = 185°

x = 185°/37°

x = 5

so,

< T = 23x - 5

<T = 23 × 5 - 5

< T = 115 - 5

<T = 110°

and

<U = 14x

< U = 14 × 5

< U = 70°

b).

Y + 88° + 112° + 90° + 135° = 540° ( Sum of angles of pentagon is 540°)

Y + 325 = 540°

Y = 540° - 325°

Y = 215°
