Question

Can anyone do 15-17 and show the work for it to plz

Answer 1

Step-by-step explanation:

In rhombus diagonals bisect each other at 90 degrees

ED=1/2BD

ED=1/2×13

ED=6.5

ED=2x+5

But ED = 6.5 [proved above]

2x+5=6.5

2x=6.5-5

2x=1.5

x=0.75

Angle BCD=42+42

Angle BCD=84

Angle BAD =84 [Opposite angles of rhombus are equal]
