Answer:
x=12 ADB= 56 BDC= 54
Step-by-step explanation:
ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation
(3x+10) + (4x-4) = 90
I combined like terms to give me 7x+6=90
Then I subtract 6 from both sides giving me 7x=84
Last I divide 7 on both sides. x=12
Then I input the x (12) into the equation and solve it from there
3(12)+10 and 4(12)-4
3(12)+10=56
4(12)-4=54
. . . I think. Hope this helps!
The answer is a 1 hour . I just had that question and got it right !!
Answer: its blurry write it out I will help you
Step-by-step explanation:
(a)
Total amount = SI + Amount
= 90 + 1800 = $1890
(b)
Total amount = SI + Amount
= 936 + 2600 = $ 3236
(c)
Total amount = SI + Amount
= 93.75 + 3125 = $ 3,218.75
