Answer:
Step-by-step explanation:
The sum of the angles on a straight line is 180 degrees. Therefore,
Angle XYZ + angle MYZ = 180
Angle XYZ + 115 = 180
Angle XYZ = 180 - 115 = 65 degrees
The sum of the angles in a triangle is 180 degrees. It means that
Angle XZY + angle YXZ + angle MYZ = 180
Therefore,
4k + 5 + 6k + 10 + 65 = 180
4k + 6k + 5 + 10 + 65 = 180
10k + 80 = 180
10k = 180 - 80 = 100
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10k/10 = 100/10
k = 10
Step-by-step explanation:
-1 / 2 + x = -21 /4
x = -21/4 + 1/2
x = (-21 + 2)/4
x = -19/4
Answer:
Your answer is 120m4
Step-by-step explanation:
Answer:
<A=143
Step-by-step explanation:
<A=<B (corresponding angles)
7x+24=3x+92
7x-3x=92-24
4x=68
dividing both sides by 4
x=17
Now <A=7x+24
<A=7(17)+24
<A=119+24
<A=143
This looks hard... good luck ! :D
