5z
Step-by-step explanation:
because I leaned it at school
The answers 59 because 90 degrees is the angle so 21 plus 10 equals 31 and 90-31 equals 59
Answer:
a)ΔFHA is similar to ΔZIA by hypotenuse side test.
reason:- angle H and angle I are of 90 degrees.
b) FH/ ZI = HA/ IA = FA/ ZA
angle F = angle Z, angle H = angle I , angle angle A = angle A
The scale factor is 3/2......( HA/IA = 12/8 = 3/2)
c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)
B. the difference between 6 and 4 is doubled ,why? becuz 6-4 is 2 and 2 is doubled by 2 and u get 4 basically 2 times 2 is 4 ..hope this helps!
