Answer:
IJ = 12
Step-by-step explanation:
sum the parts of the ratios, 3 + 3 + 4 = 10 parts
Divide HK by 10 to find the value of one part of the ratio.
40 ÷ 10 = 4 ← value of 1 part of ratio , then
IJ = 3 parts = 3 × 4 = 12
The pattern is the amount you need to add increases by 2 each time. Ex. 1+1=2 2+3=5 3+5=8
Isosceles Triangle, has 2 equal sides and angles.
