the angles of a triangle are in an extended ratio of 5:7:3. what is the measure of the smallest angle?
1 answer:
<h3>The measure of smallest angle is 36 degrees</h3><h3><u>Solution:</u></h3>
Given that,
The angles of a triangle are in an extended ratio of 5 : 7 : 3
Let one of angle be 5x
Let the other angle be 7x
Let the third angle be 3x
We know that,
Sum of angles in triangle is 180 degrees
Therefore,
5x + 7x + 3x = 180
15x = 180
Divide both sides by 15
x = 12
<em><u>Thus the angles are:</u></em>
5x = 5(12) = 60
7x = 7(12) = 84
3x = 3(12) = 36
Thus the measure of smallest angle is 36 degrees

Answer:
$1.80 + (8x$0.10)*4.5 = $5.40
Step-by-step explanation:
$1.80 base cost
$0.10 for an 8th of a mile, thus multiply by 8 = $0.80 per mile
So, $1.80 + (4.5 * $0.8) = $5.40
100<span>% × 80 = </span>100/100×80 = 80.
50 percent (50%) half it
50% × 80 = 50/100<span>×80 = 40.</span>
