Answer:
B = 50 & C = 130
Step-by-step explanation:
I really don't know how to explain but 180 - 50 = 130 for C and 50 is the measurement for B
Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
Answer:
a = 49°
Explanation:
You use the rule ‘exterior angle of a triangle’ which states that the exterior angle is equal to the sum of the two opposite interior angles.
To put it mathematically:
a + a = a + 49° (Ext angles of triangle)
a = a - a + 49°
a = 49°
7:14:21
Add 1,2,3 = 6
Divide 6 by 42=7
Then 7x1=7
7x2=14
7x3=21
