Answer:
360
Step-by-step explanation:
Formula
Sides -2 ×180
4-2=2×180=360
The only ways i thought of was 0.7, 0.70, and 0.700 .
Answer:
B
Step-by-step explanation:
2/5 (10x + 15) = 26
Distribute the 2/5
4x + 6 = 26
4x = 20
x = 5
Answer:
i don't get the way you wrote it
Step-by-step explanation:
(1-cos^2(x)) csc^2(x)=1
one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)
we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:
sin^2(x) x 1/sin^2(x) = 1
sin^2(x)/sin^2(x) =1
the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same
so then 1=1 Therefore LHS=RHS
Hope this helps
