levacccp [35]

The line of sight is the hypotenuse of a right triangle with short leg 400 m, 90 degree angle where the short leg meets the ground, an 83 degree angle at the top, and a 7 degree angle across from the right angle on the ground. Because this 7 degree angle is an alternate interior angle with the angle of depression, they are the same degree measure. Looking for the hypotenuse, we use the sin ratio: sin (7) = 400/x.

there are 11 pieces of pie left over in the cafeteria. if 6 pieces are apple and 5 are cherry, what fraction of the remaining pi

Leto [7]

Answer:

$\frac{6}{11}$

Step-by-step explanation:

we know that

To find what fraction of the remaining pieces are apple, divide the remaining pieces of apple by the total remaining pieces

we have that

the remaining pieces of apple is equal to 6

the total remaining pieces is 11

so

$\frac{6}{11}$

Find the value of x y and z below !

ehidna [41]

Answer:

$x=67, y=121, z=65$

Step-by-step explanation:

One property of parallelogram is that opposite angles have the same measure, so we can write down:

$(y-9)=112\\y=121$

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

$(z+3)+112=180\\(x+1)+112=180$

Solve the equations:

$(z+3)+112=180\\z+115=180\\z=65\\(x+1)+112=180\\x+113=180\\x=67$

To check, add up all 4 angles and check if they sum up to 360 degrees:

$x=67, y=121, z=65\\(y-9)+(x+1)+(z+3)+112=360\\(121-9)+(67+1)+(65+3)+112=360\\112+68+68+112=360\\360=360$

And please ignore the fact that I cannot insert the degree sign :(
