Answer:
36.45
Step-by-step explanation:
tan 32 = a/35
x = 23.1
tan 70 = b/23.1
y = 28.2
x^2 = a^2+b^2
= 23 .1^2 + 28.2^2
= 36.45
106.78/.05=2135.6
21356*.05=106.78
Answer:
x>4
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
x+9−9>13−9
x>4
No of substes is given by 2^n where n is the no of elements.
Here, n = 3
Therefore, number of subsets = 2^3 = 8
