If P is the incenter of JKL, find each measure
Answers
Answer:
see below
Step-by-step explanation:
angle JP = (180 - 32 - 90) + (180 - 22 - 90)
= 58 + 68
= 126°
angle JKP = (360 - JMP - JLP - LNP)/2
= 360 - (180 - 32 - 90) - 126 - (180 - 22 - 90)
2
= 360 - 58 - 126 - 68

= 54°
MP = 7
KN = 10
JP = 11 / cos(32)
= 13
PL = 17 / cos(22)

(iv) The area of a rectangle with breadth
5 cm is 30 sq. cm. Find its length and
perimeter.
Answers
Answer:
Step-by-step explanation:
if the breadth is 5cm, then you divide 30/5 to get your length since it's length times breadth to get the area, so 6cm for the length
and then it's 2b plus 2l to get your perimeter so
2(5)+2(6)=p
10 plus 12 equals p
22 is your perimeter, 6 is your length
