Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40
Nooooo but why ? Is it important
2²+2²=2*2²=2³=8
