As you can notice, the little red square at the bottom means that BAD is a total of 90 degrees.

We can add put equations and find the value of x.

15x - 2 +  7x + 4 = 90

22x + 2 = 90

22x = 88

x = 4

Solve each angle with the value of x.

Angle BAC:

15(4) - 2

60 - 2

58 degrees

Angle CAD:

7(4) + 4

28 + 4

32 degrees

Add to make sure it equals a complementary angle.

58 + 32 = 90 (correct)

Best of Luck!

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?
Kryger [21]
FV=PV(1+r)ⁿ

FV=Future Value, or the $2,600 that you want.
PV=Present Value, or the value that you are depositing.
APR: .06

2,600=2,000(1.06)ⁿ
2,600=2120ⁿ
It would take about a year for Nicole to get $2600.
