Question

Pls answer the question

Answer 1

1 . 5x-10=60........(vertically opposite angles)
therefore 5x=60+10
5x=70
X=70÷5
X=14

Answer 2

3. 60= 5x - 10                                   5. sin60 = opposite side/hypotenuse

5x = 60+10                                         =  root 3a/2a

5x=70                                                   cos 30 =adjecent sides/hypotenuse

x =70/5                                                 a/2a

x=14                                                       2a

4. qs is median

therefor by using geometric mean property

qs square =qs square* sr square

qs square = 42.25*42.25

qs square = 1785.0625

qs = 892.5(taking both side square root)
