Alright, lets get started.
We have given angle A = 40°
We are also given angle B is complement of A.
Complementary angles are two angles whose sum is 90, it means
angle B = 
angle B = 
angle B = 50° Answer
Now given, angle C is supplement of angle B.
Supplementary angles are two angles whose sum is 180°.
Means angle C = 
angle C = 
angle C = 130° : Answer
Means angle B = 50° and angle C = 130°
Hope it will help :)
The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4
Answer:
Step-by-step explanation:
Answer: -12.81% decrease
Step-by-step explanation:
1678-1463/1463 * 100 = -12.8128
Answer:
54
Step-by-step explanation:
The two angles add to 90 degrees since they are complementary
the ratio is 3:2
Multiply by x
3x:2x
Add them together and set equal to 90
3x+2x=90
5x=90
Divide each side by 5
5x/5 = 90/5
x = 18
The first angle is 3*18 = 54
The second angle is 2*18 = 36
