Answer:

Alright. The answer is A as 47, B as 43.

Step-by-step explanation:

There is a formula for this type of problem. To solve the larger number, plus the sum of the two angles and the difference, which is 90 + 4 because Complemetary angles, their sum is 90 degrees. then divide by 2, which is 47. You get the larger answer. For the smaller one, just do subtraction: 90-47=43. There!

angle B =X angle A = x+4 complementary angles= 90 degrees x+x+4= 90 2x= 86 x= 43 degrees for angle B 43+4 = 47 degrees for angle A Hope this helps
