Answer 1

Answer:

a)AB=BD

angle ADB=angle DAB=38°

angle DAE=angleDAB+ angle BAC+angle CAE

180°=38°+angle BAC+108°

180°=146°+angle BAC

angle BAC=180°-146°=34°

angle DAC=angle DAB+angle BAC

=38°+34°=72°

angle ADC+angle DAC+angle ACD=180°

(Angle sum property)

38°+72°+x=180°

110°+x=180°

x=180°-110°=70°

b)angle SRT=angle PQR +angle RPQ

(exterior angle property)

angle SRT=95°+30°=125°

In triangle SRT,

angle SRT+angle STR+angle RST=180°

(angle sum property)

125°+x+30°=180°

155°+x=180°

x=180°-155°=25°
