Construction seems to be the biggest one
Architecture, too
Answer = 72°
Complementary angles always add up to be 90.
We can write the smaller angle as x and the bigger angle as 4x, because it is 4 times bigger than x.
x + 4x = 90
5x = 90
x = 18.
This proves the smaller angle, or angle B, is 18. We know angle A is 4 times as big as 18, so we can multiply 18 x 4 to get 72.
Double check = 72 + 18 = 90
Answer:
-48+-12=. -60
Step-by-step explanation:
Well -48 +( -12)
Assume the plus sign is +1 ,multiply by 12 using the law of integers. that is +(-)= -. Then continue by subtracting -12 from - 48. with this another law is used -(-)= a plus . Like 48 + 12 =60.Then check for the number with the highest value to determine your answer for the sum you got. In this case negative 48 is the highest so it's negative 60
The first one is 1,3,31,62 and the second answer is 1,5,8
To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
45-32 = 13 / 32 *100= 40.625 round to the nearest percent is 41%
