Answer:
1156
Step-by-step explanation:
We know that,
( a + b ) ² = a² + 2ab + b²
We can follow the same method to find the value of this.
12² + 22²
( 12 + 22 ) ²
12² + 2 × 12 × 22 + 22²
144 + 24 × 22 + 484
144 + 528 + 484
672 + 484
<u>1156</u>
Let me know if you have any other questions. :)
When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:
The measurement of the angles in green is the same (are congruents)
The measurement of the angles in blue is the same (are congruents)
An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)
You know that:
![m\angle2=60º](https://tex.z-dn.net/?f=m%5Cangle2%3D60%C2%BA)
As the angle 3 is congruent with angle 2:
