Answer:
∠3 = 142°
Step-by-step explanation:
L // M
∠2 = 38° {Corresponding angles are congruent}
∠2 + ∠3 = 180 {Linear pair}
38 + ∠3 = 180
∠3 = 180 - 38
∠3 = 142°
The answer is 60 to this problem
Answer:
3 sheets of stickers
Step-by-step explanation:
he has five notebooks that have 6 stickers on them. that is 30 stickers in total. 30 stickers divided by the 10 stickers on each sticker sheet is 3. he will use 3 sheets of stickers.
trying to find the sheets of stickers
s = 5*6 / 10
and remember that you cant use half a sheet it is still using one sheet
s = 30 / 10
s = 3
We can rewrite the equation of the circle as
so that we can be in the form
When you write the equation of a circle in this form, then the center is and the radius is .
So, in our case, the radius of the circle is 10.
To find the length of the bridge, we find the two points where the bridge crosses the lake (i.e. we solve the system between the equations of the line and the circle), and compute the distance between those points:
Solving the second equation for x, we have
We use the first equation to compute the correspondent values of y:
Now, the distance between these two points is given by the pythagorean's theorem:
