No google no spam otherwise I will report that answer

Plz send me answer quick...It’s urgent .........

Answer 1

Step-by-step explanation:

C+39+90=180 (triangle abc and becaus of a rectangle angle at b is 90)

C=180-39-90

C=51

In triangle EDC because of transversal angle at c will be 51

So

D+78+51=180 angle sum in a triangle

D=51.

Part A

B+54+90=180 (angle sum in triangle abc and a rectangle)

B=36

a=b=36 because of transversal (alternate interior angles AB parallel to DC)

Answer 2

Step-by-step explanation:

1)a°=46°

every angle of rectangle is 90°

angle C=90°

90°=a°+54°

90-54=a°

46°=a°

2)b°= angle A=

as you can see there is a triangle which is triangle CAB

every triangle is 180°

triangle CAB=angle C+angleA+angleB

180°=54°+90°+angle b

180°=134°+angle b

180°-134°=+angle b

46°=angle b

note=I didn't take full angle A i just take that angle which was included in triangle

in second diagram

3)angle c°

every angle of rectangle is 90°

in right angle ∆ CEB

angle C=39°,angleB=90°

180°=39°+90°+anglec°

180°=129°+angle c°

180°-129°=angle c°

51°=angle c°

4)d°=

angleC=90°

90°=angle X+39°...they didn't give the name so let's just take anglex

90°-39°= angle X

X=51°

in triangle CED

Every triangle is 180°

triangle CED=180°

180°=d°+78°+51°

180°-129=d°

51°=d°
