Answer:
The measures of the other interior angles are 15° and 105°
Step-by-step explanation:
The given parameter of the measures of the interior angles of the triangle are;
The measure of one of the interior angle of the triangle = 60°
The ratio of the measure of the other interior angles = 1 : 7
Let the x represent one of the other interior angles and y represent the third interior angle, we have;
x + y = 180 - 60 = 120
x : y = 1 : 7
x = 1 part of 8 parts of 120°
y = 7 parts of 8 parts of 120°
Therefore;
x = 1/(1 + 7) × 120 = 1/8 × 120° = 15°
x = 15°
y = 7/(1 + 7) = 7/8 × 120° = 105°
y = 105°
The measures of the other interior angles are 15° and 105°.

Explanation:
What is the cost when the two plans cost the same?
Answer:
550 miles and 128.50
Step-by-step explanation:
57 + 0.13 x = 46 + 0.15 x
57 - 46 = 0.15 x - 0.13 x
11 = 0.02 x
x = 11 / 0.02 = 1100 / 2 = 550 miles
cost = 57 + 0.13 . 550 = 128.50
