Answer:
?=84
Step-by-step explanation:
From the diagram;
Also the interior angles of a triangle adds up to 180 degree.
x+y+90=180
60+y+90=180
y==180-150
y=30
Also, we use angles on a straight line to get;
z+114=180
z=180-114
z=66
Again using sum of interior angles of a triangle, we get;
z+y+?=180
66+30+?=180
96+?=180
?=180-96
?=84
Your answer would be C. 2
123. angle 1 would be the same as angle 5, seeing as the lines are parallel. 5&1 are both on top on lines A & B AND on the same side of transversal
Answer:
21, 42, 63, 84
Step-by-step explanation:
3x7=21
Because of this all multiples of 21 will be common multiples of 3 and 7
