Answer:
About 60.77 feet
Step-by-step explanation:
Attached pic.
Blue line is of Bethany
Green line is of Ben
Red line is the distance between them [what we are trying to find]
We can use pythagorean theorem that tells us:

Where c is the hypotenuse of the right triangle [red lines in both respective triangles]
and
a, b are the two other sides of the triangle
Left Triangle (using pythagorean theorem):
Base is 30
Left side is 20 - 10 = 10
So,

Right Triangle (using pythagorean theorem):

Distance between Bethany and Ben = 31.62 + 29.15 = 60.77 feet
Answer:
Step-by-step explanation:
If 70 is 50% then 140 is 100%.
c is 75% of 140 = 105
a is 25% of 140 = 35
b is 100% of 140 =140
Answer:
cos(z) = .3846153846 and angle z = 67.38°
Step-by-step explanation:
Side UV is corresponding to side YX. Side VW is corresponding to side YZ. Side UW is corresponding to side XZ.
Starting with the first corresponding pair, we are told that side UV is 36, and that side YX is 3/5 of that. So side YX is

We are next told that side VW is 39, so side YZ is

In order to find the cos of angle z, we need the adjacent side, which is side XZ. Side XZ is 3/5 of side UW. Right now we don't know the length of side UW, so we find it using Pythagorean's Theorem:
and
so
UW = 15
Now we can say that side XZ is

The cos of an angle is the side adjacent to the angle (9) over the hypotenuse of the triangle (23.4) so our ratio is:

which divides to
cos(z) = .3846153846
If you need the value of the angle, use the inverse cosine function on your calculator in degree mode to find that
angle z = 67.38°
Answer:
1.9 as a decimal
1 9/10 as a fraction
Step-by-step explanation:
45 + 50 = 95
95/50 = 1 9/10
1 9/10 = 1.9
