(0,10) and (0,4)
Step-by-step explanation:
7-3=4
7+3=10
Answer:
BC = 2.24 cm
AC = 1.99 cm
Step-by-step explanation:
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin θ = o/h
cos θ= a/h
tan θ = o/a
θ = 40°
h = 3cm
a = AC
o = BC
first let's calculate BC
sin θ = o/h
o = sin θ * h
o = sin 40 * 3
o = 0.7451 * 3
o = 2.24 cm
BC = 2.24 cm
having one leg and the hypotenuse we can calculate the other leg with pitagoras
h^2 = c1^2 + c2^2
3^2 = 2.24^2 + AC^2
9 = 5.02 + AC^2
AC^2 = 9 - 5.02
AC = √ 3.98
AC = 1.99
Answer:
12
Step-by-step explanation:
The constant of proportionality in direct variation has this formula with a being the constant of proportionality:
Column 1 has the x-values and Column 2 has the y-values. If you divide the x-values by the corresponding y-values, you will get an value of 12.
Solution: x=5, top angle=80, bottom angle=100
Step by step solution:
Since they are same side interior angles they are equal to 180 so we can set up an equation.
19x+5+17x-5=180
36x=180
x=5
Then plug in the x value in the original equations
19(5)+5=20(5)=100
17(5)-5=16(5)=80
Hope that helps :)
To answer this we will divide 32 (total elephants) by 4 (times more).
32 ÷ 4 = 8
Check your work:-
8 × 4 = 32
We were right! :)
So, there were 32 elephants.
Hope I helped ya!!!!!!!!!!
