A full circle is 360 degrees, so subtract your other values from that, making 178. The opposite angle is a right triangle, which is 90 degrees. So that means angle ED is 88 degrees.
U = 3 hours since 3 is the least amount of time it would take underwater. Hope this helped
Answer:
5
Step-by-step explanation:
If two is subtracted from a number: let's give the number a name and call it X . And this difference is tripled: so we get 3(X−2) . The result is 4 more than the number, so
3(X−2)=4+X .
We want to know X so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:
3X−6=4+X.
Now subtract X and add 6 :
2X=10
Divide by 2:
X=5
Answer:
x = 198
Step-by-step explanation:
1/2x + 101 = 200.
Subtract 101 from both sides.
1/2x = 99
You want x by itself, therefore you have to get rid of 1/2. The opposite of diving by two, is multiplying by two.. therefore, you must multiply both sides by two.
x=99*2
x=198
By the Triangle Angle-Sum Theorem, all the angles in a triangle have to add up to equal 180. Therefore, 180-35-88=57, second choice down.
