Hi... DD working through "Michael Gove's" papers as she calls them and has come across two things to calculate that they haven't covered and she can't find in her Maths books.... I've had a look and I can't either! She's an Add Maths student so is convinced she should be able to work it out and is missing something obvious....
So hoping someone can tell us HOW to do one or both of these?
- The area of a kite to 3 significant figures. Two adjacent sides are 6.4 cm and 9.7 cm and the angle between them is 110 degrees. That's it... in a diagram obviously!
- A quadrilateral:
Corners are M - N - P - L
Asks for size of angle of MLP to 3 signify figures
Info given (in diagram) is:
LMN: 58 degrees
NPL 72 degrees
PNM not given
SIdes: MN 13.7 cm, NP 4.3 cm, PL 15.6 cm
Huge thanks and think Ill be kicking myself when someone tells me ... ages ago I did Maths A level.....
