x = 70°
<u>Explanation</u> :
To find : Value of x
Here, given angles are :
35°, 75° and x
Knowledge Required to solve it :
The sum of all the angles of a triangle is 180°.
Now,
35°+75°+x=180°
⇒110°+x=180°
⇒x=180°-110°
⇒x=70°
.°. x=70°
The opposite of multiplication is division, so if you take the signaler number after the equal sign divide it by the number before and it will give you the missing number like this:
(I'm only going to do a few and then you try it. I can check it when you are done)
6 x ____ = 60 <<<Divide 6 by this number
60 ÷ 6 = 10
6 x 10 = 60
140 ÷ 10 = 14
140 = 14 x 10
500 ÷ 50 = 10
50 x 10 = 500
Hope this helps!
18-6=12 12/2= 6, the answer is 12 or 18.
