Answer:
7
Step-by-step explanation:
12b -b = 11b
11b = 77
Divide both sides by 11
b = 7
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>.
If you give me the equation I can simply it for your
angle 2 is also 65º because they are corresponding angles. Using the vertical angles theorem, you can also say that angles 3 and 7 are 65º. so the answer to your question would be angle 3
