Answer:
DE=6
Step-by-step explanation:
DE+EF=DF
9x-12+x+10=18
10x-2=18
10x=18+2
x=20/2=10
DE=9x-12 ⇒ 9(2)-12=18-12=6
DE=6
sin 40° = 0.6428
<u>Step-by-step explanation:</u>
The complementary ratio of sine is cos and vice-versa.
sin θ = cos (90 - θ)
cos θ = sin (90 - θ)
So cos 50° = sin (90 - 50)°
= sin 40°
sin 40° = 0.6428
This indicates that the complement of cos 50° is sin 40° which is equal to 0.6428.

Answer:
A = 36 cm²
Step-by-step explanation:
Given
A = ( a + b)
substitute h = 12, a = 2 and b = 4 into the formula, thus
A = (2 + 4) = 6(6) = 36 cm²
