<h3>The measure of angles of triangle are 96 degree, 36 degree and 48 degrees</h3>
<em><u>Solution:</u></em>
The ratio of the measures of the angles in a triangle is 8:3:4
Let the first angle be 8x
Let the second angle be 3x
Let the third angle be 4x
We know that,
sum of all angles in triangle is 180 degrees
Therefore,
8x + 3x + 4x = 180
15x = 180
x = 12
Thus,
First angle = 8x = 8(12) = 96
second angle = 3x = 3(12) = 36
third angle = 4x = 4(12) = 48
Thus measure of angles of triangle are 96 degree, 36 degree and 48 degrees

Answer:
- P(Take the bus U Walk) =3/5
Step-by-step explanation:
According to table we can find that
Number of students taking the bus:
Number of students walking to school:
Number of students either take the bus or walk:
Required probability is:
- P(Take the bus U Walk) =
- (number of students either take the bus or walk) / (total number of students) =
- 60/100 =
- 3/5

Answer:
Step-by-step explanation:
<u>Goal</u>
- Find the equation of the line.
<u>Given</u>
- Coordinate points which are (4,3) and (6,2).
<u>Step</u><u> </u><u>1</u>
- Find the slope by using slope formula or rise over run.
Substitute the coordinate points in
<u>Step</u><u> </u><u>2</u>
- Rewrite the equation in slope-intercept form by substituting m = -0.5
Substitute m = -0.5
<u>Step</u><u> </u><u>3</u>
- Find the value of b by substituting any given coordinate points in the equation.
<em>Substituting</em><em> </em><em>both</em><em> </em><em>coordinate</em><em> </em><em>points</em><em> </em><em>still</em><em> </em><em>give</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>answer</em><em>.</em><em> </em>
<u>Step</u><u> </u><u>3.</u><u>1</u>
- Substitute (4,3) in the equation.
<u>Step</u><u> </u><u>3</u><u>.</u><u>2</u>
- Substitute (6,2) in the equation.
<u>Step</u><u> </u><u>4</u>
- Rewrite the equation again by substituting the value of b.
Substitute b = 5 in the equation.
Hence, the equation is y = -0.5x + 5
