The 3 inside angles of a triangle equal 180.

Add the 3 angles together to equal 180:

X + (5x-20) + 4x = 180

Simplify the left side by adding like terms:

10x-20 = 180

Add 20 to each side:

10x = 200

Divide both sides by 10:

x = 20

Angle A = x = 20

Angle B = 4X = 4(20) = 80

Angle C = 5x-20 = 5(20) -20 = 100-20 = 80

Answer:

Step-by-step explanation:

The equation to solve is:

$Sin(33)=\frac{7}{x}$

Sin 33 has a value in the calculator. We simply cross multiply and do algebra and solve:

$Sin(33)=\frac{7}{x}\\Sin(33)*x=7\\x=\frac{7}{Sin(33)}\\x=12.85$

Rounding to 1 decimal place, we have:

12.85 = 12.9

Answer choice B is right.

Answer:

The principle applied for second month payment is $1,339.13

B is correct

Step-by-step explanation:

Mortgage value = $231,450

APR = 4.65%

Monthly Payment = $2,236

First month interest of $231,450 of APR 4.65%

Interest $=231450\times \dfrac{0.0465}{12}$

Interest of first month = $896.87

Monthly payment = $2,236

Second month's payment is applied toward the second month's principal

= Monthly Payment - First month Interest

= 2236 - 896.87

= 1339.13

Hence, The principle applied for second month payment is $1,339.13
