Answer:
x = 15
arc PQ = 110°
ΔPQR is an acute triangle
Step-by-step explanation:
(6x) + (8x-10) + (10x+10) = 360°
combine like terms:
24x = 360°
x = 15
arc PQ = 8(15) - 10° = 110°
Answer:
4n^2+3n+2
Step-by-step explanation:
9 24 47 78 117
15 23
8
8/2 = 4
=4n^2
9-4 = 5 (the minus value come from 4n^2 where n is the position where 9 lays)
24-16 = 8
47-36 = 11
so plus 3 every time so 3n
4n^2+3n for the first value is 7 so you need an extra 2
4n^2+3n+2
Answer:
Step-by-step explanation:
b) 1- scale factor from the first map to the second map:
= 1.33
2- landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm.
Side lengths of the landmark on the second map
Divide the length by scale factor:
side lengths of 3 mm: = 2.25 mm
side lengths of 4 mm: = 3.007 mm
side lengths of 5 mm: = 3.75 mm
