X would equal 70°.
For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.
I hope this helps!
Answer:
Step-by-step explanation:
The ratio is simply the division of one by another (and simplification).
Hence, <u>the ratio of production of the first line to the second line</u> is 1250 divided by 2825. So,
Ratio = 
The length of the yard is 25ft.
In order to find this we first need to set up variables for the length and the width. Since we don't know anything about the width, we'll set it as x. Then, we know the length is equal to ten more than three times the width. Since the width is x, we can write the length as 3x + 10. Now we can use the formula for the perimeter of a rectangle to solve for x.
2l + 2w = P
2(3x + 10) + 2(x) = 60
6x + 20 + 2x = 60
8x + 20 = 60
8x = 40
x = 5
Now that we have a value for x, we can plug into the length equation and find the length.
3x + 10
3(5) + 10
15 + 10
25
5a^3 + 3b^4
insert the numbers into the equation.
5(4)^3 + 3(-5)^4
evaluate
5(64) + 3(625)
evaluate
320 + 1875
the solution is:
2195
