Answer:
The measure of a = b = 116 degrees
Step-by-step explanation:
Here, we have value of angles to calculate.
If a and b are both supplementary to c, what this means is that when we add either a or b to c, we get 180
Hence; Mathematically;
a + c = 180 and b + c = 180
What we have here is that a and b must be equal since they are both supplementary to the same angle value
Now, we are told further in the question that the measure of angle a is 12 less than 2 times the measure of c;
Mathematically, this means that;
a = 2c - 12
So we now want to find the measure of b
Let’s substitute for a
2c -12 + c = 180
3c -12 = 180
3c = 180 + 12
3c =192
c = 192/3
c = 64
Thus; a = 2c - 12 = 2(64) -12 = 128 -12 = 116
Answer:

Answer:
The number is 10
Step-by-step explanation:
Of means multiply and is means equals
125% * Number = 12.5
Change to decimal form
1.25 * Number = 12.5
Divide each side by 1.25
1.25 * Number / 1.25 = 12.5/1.25
Number =10
Answer:
n=15
Step-by-step explanation:
(n-2)180=2340
n-2=2340/180=13
n=15
