Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked

Well, since it only asking about the product, you don't have to multiply the result
The product would be :
3 x 2 = 6
3x 20 = 3 x 2 x 10 = 60
3 x 200 = 3 x 2 x 10 x 10 = 600
hope this helps
Look it up on youtube i just had this question and the video helped me a lot
