For δabc, m∠a = 2x m∠b = x m∠c = 3x what is m∠c? a. 20° b. 30° c. 90° d. 120°

The sum of the 3 angles of a triangle need to equal 180 degrees.

Using the information in the problem you have:

2x + x + 3x = 180

Simplify:

6x = 180

Divide each side by 6:

X = 180 / 6

x = 30

Angle C = 3x = 3(30) = 90 degrees.

The answer is C.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
