Attached the solution and work. The red dotted area is all the solutions.
Answer:1. Angle BDA and angle BEA are the same angles.
2.AB is the bisector of the quadrilateral (It splits it in half turning it into two triangles that are exactly the same).
Step-by-step explanation:
1 1/4*30=37.5 because, first to make this easier to work with I like to turn the fraction into a decimal like so, 1/4=.25 because 1/4=.25 so 1/4=.25, so now we have 1.25*30=? What this is pretty much saying is that 30+(25% of 30)=? Which to solve this we just need to find how much 25% is of 30 which is .25*30=7.5 because 7.5*4=30 making it true that this is 25% of 30. Now what we have to do is take 30+7.5 (because we have a 1 infront of the 25% we add this instead of subtract it, if we had no whole number infront of the 30 and where solving this that way we would have to subtract instead of add) which adds up to be are end answer of 37.5.
Hope that this helps and makes sense, Enjoy!=)
1. Integers numbers are defined as the set of numbers that is formed by Positive numbers, which are also called "Natural numbers"; Negative numbers (They are less than zero) and zero (This has no sign). This set is represented with the letter "Z". Therefore: Z={...-2, -1, 0, 1, 2 ...}.
2. So, if 12 is added to the square of a positive integer, you can write the following the expression:
12+x²=133
3. You can obtain the value of the positive integer "x", by clearing it. Then, you have:
12+x²=133
x²=133-12
x=√(133-12)
x=√121
x=11
Therefore, the positive integer is: 11
Answer:
h = -32.7
Step-by-step explanation:
8.44 = 34.6 + 4h / 5
-26.16 = 4h/5 (First off we subtract 34.6 from each side, to make it easier to solve)
-26.16 = 0.8h (Then, we turn 4h/5 into 0.8h since 4h / 5 = (4/5)h.)
-32.7 = h (Divide both sides by 0.8..)
h = -32.7 (And voila!! Your answer is right there!)
