Since a straight line is equal to 180, 180-65 will be equal to x. 180-65 = 115, so x = 115

As you leave? Clark, the sign says Lutherville 150 ?miles, Otisburg 240 miles. If the Planet Diner is halfway between Luthervill

eimsori [14]

$\bf Clark\rule[0.35em]{7.8em}{0.25pt}\stackrel{150}{Lutherville}\rule[0.35em]{4em}{0.25pt}Planet Diner\rule[0.35em]{4em}{0.25pt}\stackrel{240}{Otisburg}$

the distance between Lutherville and Otisburg is 240 - 150 = 90.

Planet Diner is half-way between them, half of 90 is 45.

Planet Diner is 45 miles from Lutherville.

from Clark to Lutherville is 150 miles, and from Lutherville to Planet Diner is 45 miles, thus from Clark to Planet Diner is 150 + 45 = 195.

4 11/18-x=1 31/36 whats the answer

marishachu [46]

Answer:

$\large\boxed{x=2\dfrac{3}{4}}$

Step-by-step explanation:

$4\dfrac{11}{18}-x=1\dfrac{31}{36}\qquad\text{subtract}\ 4\dfrac{11}{18}\ \text{from both sides}\\\\4\dfrac{11}{18}-4\dfrac{11}{18}-x=1\dfrac{31}{36}-4\dfrac{11}{18}\\\\-x=1\dfrac{31}{36}-4\dfrac{11\cdot2}{18\cdot2}\\\\-x=1\dfrac{31}{36}-4\dfrac{22}{36}\\\\-x=1+\dfrac{31}{36}-4-\dfrac{22}{36}\\\\-x=(1-4)+\left(\dfrac{31}{36}-\dfrac{22}{36}\right)\\\\-x=-3+\dfrac{31-22}{36}\\\\-x=-3+\dfrac{9}{36}$

$-x=-3+\dfrac{9:9}{36:9}\\\\-x=-3+\dfrac{1}{4}\qquad\text{change the signs}\\\\x=3-\dfrac{1}{4}\\\\x=2\dfrac{4}{4}-\dfrac{1}{4}\\\\x=2\dfrac{4-1}{4}\\\\x=2\dfrac{3}{4}$

Will Thank and badge! Please answer

-Dominant- [34]

Find the value of θ,
θ = arccos -8/9 = 152.734 deg
You can substitute this value for the requirement.
tan 152.734 = -0.51539
sin 152.734 = 0.45812
