Tenth place is the answer!! :))
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.
Answer:
18 ways
Step-by-step explanation:
The computation of the number of ways that could be choose your dinner as follows:
= 3 meat choices × 3 vegetable choices × 2 desserts
= 18 ways
By multiplying all the three things we can determined the number of ways
Answer:(x,y) x+5,y-3)
Step-by-step explanation: tea
B
calculate the slopes m of the 2 lines using the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = C(- 2, 4) and (x₂, y₂ ) = D(0, - 4 )
= 
= 
= - 4
repeat with (x₁, y₁ ) = F(- 4, 0 ) and (x₂, y₂ ) = G(4, 2 )
= 
= 
= 
The 2 lines are perpendicular because their slopes are negative reciprocals
