We can use tangent to calculate the length of ST.
Here, the opposite side of the 60 degree angle is ST, and the adjacent is RS. Plug in what we know, we can use 'x' for side ST:
Solve for 'x', multiply 7 to both sides of the equation:
This is an exact answer for the length of ST, we can find an approximate with a calculator:
Answer:
$809.32
Step-by-step explanation:
The loan amount is 80% of $150,000, or $120,000. The monthly payment of principal and interest is $586.82.
The total annual expense for taxes and insurance is $1920 +750 = $2670, so the monthly expense is $2670/12 = $222.50.
Then the total of payments for mortgage and escrow will be ...
$586.82 +222.50 = $809.32
__
The monthly P&I payment is given by ...
A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . . where i is the annual interest rate, t is the number of years, and P is the amount financed.
A = $120,000(0.042/12)/(1 -(1 +0.042/12)^(-12·30)) ≈ $586.82
__
A spreadsheet or financial calculator can be useful for calculating payments, though the formula isn't difficult to use.
You change the Y sign.
L = 1, -2
Q = 4, 1
G = 3, -4
You're looking for something like y=2x+3 and 2y=4x+6?
Answer:
The triangles are congruent.
Step-by-step explanation:
Don't let those little lines mess up. Both triangles have the same shape and size. They are congruent.
