Cellular phone service that charges per-minute will charge $70 for 270 minutes. How much would 1260 minutes cost? Round your ans
gulaghasi [49]
$70 = 270 min
x = 1260 min
Where x is the charge of phone service per 1260 min.

Cross multiply:
1260 * 70 = 270 * x
88200 = 270x
88200/270 = x
x = 326.67

The total charge of cellular phone service for 1260 min is $326.67

Given: <br> ΔABC, m∠C = 90º, m∠B = 30º<br> CM - angle bisector<br><br> Find: m∠AMC
SashulF [63]

Answer:

75°

Step-by-step explanation:

1. Consider right triangle ABC. In this triangle

m∠C = 90º and CM - angle bisector.

If CM is angle C bisector, then

m∠ACM = m∠MCB = 45º

2. Consider triangle CMB. The sum of the measures of all interior angles of the triangle is always 180°, then

m∠MCB + m∠CBM + m∠BMC = 180°,

m∠BMC = 180° - 45° - 30°

m∠BMC = 105°

3. Angles AMC and BMC are supplementary angles, so

m∠AMC + m∠BMC = 180°

m∠AMC = 180° - 105°

m∠AMC = 75°
