What is the chemstry expiements this does not help much
Answer:
x=90° and y=35°
Step-by-step explanation:
to get x and y first you must find the middle angles based on the information you have so:
35+90+n=180° solve for n to get what the middle angles are (since they are vertical angles they are equal) so the middle angles are both 55 degrees
and then 180-x=that angle that is also on the line with x so we'll call it k
so k+55+y=180°
we can see that y equals 35* because I noticed that those are parallel lines on the outside of the triangle so 35* and y angles are congruent and y =35°
now 35+55+k=180°
solve for the angle next to x which we called k and it is 90°
so x=90° and y=35°
after all this math I realized that if they are parallel lines then we can just use that to figure it out so use the properties to find out that x=90° and y=35°
A=30
Multiply base times height and then divide by 1/2
(3 3/4)(4)=15
15/(1/2) = 30
Answer:
6
Step-by-step explanation:
So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:
And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:
To find the number, we just need to find x. Thus, subtract 2 from both sides:
Divide both sides by 8:
And we're done!
So, our original number was 6.
