The discriminant determines the number of real solutions. If the discriminant is positive, there will be two solutions. If it's negative, there are no solutions. If it's 0, there is one solution

For what value of x does mz1 = 90° ?<br> 100°<br> x + 10)
sp2606 [1]

Answer:

You can solve this with common sense, but I'll do it for you and read my explanation before you demand an answer.

Step-by-step explanation:

When you look at a right angle, one forms 90°

A square has 4 sides, each should measure 90°.

That is how we know that point C measures 90°.

Now let's solve for x.

100+(x+10)+90°=90°

Solve the equation:

100+x+10+90=90

Step 1 : Solve for both sides.

100+x+10+90=90

(x)+(100+10+90)=90 ADD LIKE TERMS!

x+200=90

Step 2: Subtract 200 from both sides so you can make them equal.

x+200−200=90−200

x=−110

So, we get that <em>x=-110</em>. So <em>the blank side</em> should measure <em>90 degrees</em>.

How do you solve this problem, it's confusing for me.
tatyana61 [14]
If 28 is the distance that he is from the starting point then
so 10 to the right
+10
then 3 to the left
-3powerjump
10-3pj
total jump length must be to the left because 10 is less than 28 and he can't jump negative feet
absolute value
|10-3p|=28
since we assume that he jumped 28 feet to the left, we can assuume
10-3p=-28
subtract 10 from both sides
-3p=-38
divide by -3
powerjump=12 2/3

or if the problem is he jumped 28 feet in total then
10+3p=28
subtract 10 from both sdies
3p=18
divie by 3
powerjump=6
