One angle of a triangle measures 65°. The other two angles are in a ratio of 3:20. What are the measures of those two angles?

Nataly_w [17]

Answer:

15° and 100°

Step-by-step explanation:

$65 + 3x + 20x = 180$

$23x = 115$

$x = 5$

3 × 5 = 15, 20 × 5 = 100. So the other two angles measure 15° and 100°.

Y and x have a proportional relationship and y=9 when x=2 what is the value of y when x=3

Paladinen [302]

If they are proportional, then y/x should always be the same.

So 9/2= 4.5

We need to find the y value at x=3 to make y/x equal 4.5

4.5 = y/3

y = 4.5*3 = 13.5
