Solve the proportion using number sense. 2/8 = x/ 48
1. 6
2. 12
3. 16
4. 8
8 * 6 = 48
so what is 2 times 6 ?
or another way
1/4 * 48 = 12
Solve the proportion using cross products. 18/20 = k/110
1. 99
2. 122
3. 3.3
4. 2.9
20 k = 18*110
2 k = 18 *11
k = 9 * 11
Are the ratios 8/12 and 10/25 proportional? Explain
8/12 = 2/3
10/15 = 2/3 so no way 10/25 is 2/3

We know: The sum of the measures of the angles of a triangle is equal 180°.
We have: m∠A =65°, m∠B = (3x - 10)° and m∠C = (2x)°.
The equation:
65 + (3x - 10) + 2x = 180
(3x + 2x) + (65 - 10) = 180
5x + 55 = 180 <em>subtract 55 from both sides</em>
5x = 125 <em>divide both sides by 5</em>
x = 25
m∠B = (3x - 10)° → m∠B = (3 · 25 - 10)° = (75 - 10)° = 65°
m∠C = (2x)° → m∠C = (2 · 25)° = 50°
<h3>Answer: x = 25, m∠B = 65°, m∠C = 50°</h3>
