Answer:
hello attached below is the sketch of the missing diagram
a) h = 2
b) cos^-1 ( 2 ) = ∞
c ) θ ≈ 215°
Step-by-step explanation:
a) The length ( h ) to the right of the circles center
= h^2 = ( -1.15)^2 + ( -1.64)^2
∴ h = 2
b) cos^-1 ( 2 ) = ∞
c) The value gotten from b does not give us the value of θ
AB = - 1.64
BC = -1.15
AC = 2
sin^-1 ( - 1.64 / -1.15 )
cos^1 ( -1.15 / 2 ) gives us the value of θ
tan^-1 ( -1.64 / -1.15 )
∴ θ ≈ 215°
These lines are perpendicular because y = -6 is a horizontal line with a slope of 0 and x = 6 is a vertical line with an undefined slope
Answer:
4
Step-by-step explanation:
We know the other side of the rectangle is 18.
So 18=10+2x
subtract 10
8=2x
divide by 2
x=4
Dina : Yana : Difference
4 :1 : 4-1
4: 1: 3
she threw away 26 and is now 2 less (which means if she has threw away 24, they wil have the same)
Given from the ratio above, the difference is 3 parts
3 parts = 24
1 part = 24 ÷ 3 = 8
4 parts = 8 x 4 = 32
Dina had 32 at first
Answer:
B. 52 units
Step-by-step explanation:
Here we have to count the length we need count the number of units passed from P.
= 7 + 12 + 8 +6 +6 +4 + 2 +3
= 52 units
Here with I have attached the figure.
