The measure of B will be given by:
cos θ= adjacent/hypotenuse
θ=B
adjacent=a=2
hypotenuse=c=√5
thus;
cos B=2/√5
thus
B=arccos 2/√5
B=26.565°~26°
A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K <span>∪ L.
You simply must combine the two sets together without repeating any of the same numbers.
K </span><span>∪ L = {2, 3, 5, 7, 8}.</span>
For the first one, the GCF=1. You cannot factor this any further.
For the second one, the GCF=2y(2y^2+3y+6).
Answer:
29
Step-by-step explanation:
Step-by-step explanation:
84 = 2(l+b)
L+b = 84 / 2
L+b = 42
There fore..
Length is 42 and breadth is 42 - 8
