Megan constructed triangle ABC. In Megan's triangle,
mZA is represented by xº, mZB is 4 times greater than
mZA, and mZC is 30° less than 5 times m ZA.
mZA= x
mZB = (4x)
m2C = (5x - 30)

21°, 84°, 75° are the angles

Step-by-step explanation:

Total angle in a triangle is 180.

x + 4x + (5x - 30) = 180

10x - 30 = 180

10x = 210

x = 21°

Angles are:

A: 21°

B: 4(21) = 84°

C: 5(21) - 30 = 75°

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
