Answer: 23+32-3×4-52÷5+(7×4)= 60.6
Step-by-step explanation:
Step-by-step explanation:
Given :
1- cosA = 1/2
or, CosA = 1 -1/2
Therefore ; CosA = 1/2 = b/h
According to the Pythagoras theorem,
P = root under h^2 - b^2
= root under (2)^2 - (1)^2
= root under 4 -1
= root 3
Again,
SinA = P/h
= root 3 / 2
Answer:
y < 4x - 2
Step-by-step explanation:
Answer:
<em>1, 4.5</em>
Step-by-step explanation:
for midpoint
x₁ = -2, y₁ = 0
x₂ = 4, y₂ = 9
for midpoint
(x₁+x₂)/2 , (y₁+y₂)/2
(-2+4)/2 , (0+9)/2
2/2 , 9/2
1, 4.5
