Step-by-step explanation:
the picture isn't realistic but mathematically it's:
1) = 121°
2) = 59°
7, 9,11,13 odd integrates
1)
=> <span>m∠2 = 2x +13
=> </span><span><span>m∠1 = </span> 4x - 1
Since YP angle bisector the angles with be equal to each other,
</span>
m∠1 = <span>m∠2
2x + 13 = 4x - 1
2x - 4x = -1 -13
-2x = -14
x = 7
</span>
All other questions are to be done in that way, don't be lazy :P
One decimeter equals 10 centimeters. So 3 decimeters equals 30 centimeters. They are equal.
