Question

Could someone please help me with these two questions (photo included)

Answer 1

Answer:

7) m<SCA= 3x+3=90°

(since all the angles of a square are right angle)

=>3x=87°

=>x= 29°

8)Opposite angles of a rhombus have equal measure.

So, half of opposite angles of a rhombus have equal measure .

m<1=m<4=37
