Answer:
140°
Step-by-step explanation:
The sum of angle of a triangle is equal to 180°.
Two of the angles measured 20°.
We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,
20+20+x = 180
40+x = 180
x = 180-40
x = 140°
So, the third angle of the triangle is 140°.
You need an answer to get x. like it needs to be
10x+44=100 or something in order to find x
That is also equal to (9÷1)÷3, so it will be the same as 9÷3. Therefore, the answer is 3.
The equation would be 4+x

13.
Subtract 4 from both sides. The four on the left would cancel out and the 13 on the right would now be a 9. Therefore, the answer is
