Answer:
x = 6
Step-by-step explanation:
The two angles are marked as being equal, so the line down the middle of the triangle is an angle bisector. An angle bisector divides the sides of the triangle proportionally, so you can write the proportion ...
x/12 = 5/10
x = 12(5/10) . . . . multiply by 12
the sum of angels of a triangle is 180°
130+ ? + (180-160) = 180
130+ ? +20= 180
150+ ? = 180
? = 30°
the missing angle is 30°
1. Thirty two million five thousand and eight
2. 30,000,000+ 2,000,000 + 5,000 + 8
5a plus 5 minus 3a is equal 13
0
x = 2
2 x 3 = 6 + 5 = 11
2 - 2 = 0
