If abcd ≅ qrst, m∠a = x - 10, and m∠q = 2x - 30, what is m∠a?

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

the answer would be 0.54
