Examples of natural fibres are cotton and silk whereas examples of synthetic fibres are: nylon, polyester, etc. Silk is a type of natural fibre or animal fibre.
Step-by-step explanation:
Answer:
Step-by-step explanation:
sec (-x)-sin (-x) tan (-x)=cos x
sec(x)-(-sin x)(-tan x)=cos x
1/cos x-sin x(sin x/cos x)=cos x
multiply by cos x
1-sin ²x=cos²x
or 1=sin²x+cos²x
which is true.
Answer:
D) the value of x is 135, because the angles shown in each diagram are complementary
Step-by-step explanation:
Each diagram has 2 angles labeled, and those two angles are always supplementary. The sum of the measures of two supplementary angles is 180°.
x + 45 = 180
x = 180 - 45
x = 135
Answer: D) the value of x is 135, because the angles shown in each diagram are complementary
Answer:
2nd option is correct answer
Answer:
W = 1.4119
Step-by-step explanation:
Is means equals and of means multiply
W = 7% of 20.17
Change to decimal form
W = .07 * 20.17
W = 1.4119
