Answer:
(-3,2)
Step-by-step explanation:
From the number line graph we can see that there is a open circle at -3
and an open circle at 2.
The shaded part lies between -3 and 2
So we can write inequality form as -3<x<2.
Interval form
If we have open circle then we use parenthesis when we write it in interval notation. we have open circle at -3 and 2
So interval notation is (-3,2)
Answer: Answer is D (-3,2)
Q2. angle 5 +angle 6=90°
angle 5+ 6°=90°
angle 5=90°-6°
angle 5=84°
Q.3 angle 8+angle 9=90°
angle 8 + 11°=90°
angle 8=90°-11°
angle 8=79°
1 : 4 : 9
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9
