Answer:
Step-by-step explanation:
Given: Perimeter of triangle= 72 units
Measure of one of the side= x units
Measure of second side = 3x units
We know the perimeter of triangle is equal to sum of all sides.
Now, finding the possible value of x
forming an inequality to determine the value of x
Remember triangle has three sides, however, measure of only two sides are given.
⇒ 
⇒ 
Dividing both side by 4
⇒ 
∴ The inequality to represents all possible values of x is
Answer
7,3'
hope this helps give me a 5-rate and a thanks!
Answer:
Option (3) and Option (5)
Step-by-step explanation:
By the property of a triangle,
Sum of interior angles of a triangle is 180°.
m∠Q + m∠R + m∠S = 180°
By substituting the measures of angles in the equation,
(8x - 17)° + (19x + 4)° + (5x + 1)° = 180°
32x - 12 = 180
32x = 192
x = 6
m∠Q = (8x - 17)° = 48 - 17
= 31°
m∠R = (19x + 4)° = 114 + 4
= 118°
m∠S = (5x + 1) = 30 + 1
= 31°
Since, one interior angle measures 118° which is grater than 90°.
Therefore, triangle QRS is an obtuse triangle.
Since, m∠Q = m∠R = 31°
It's an isosceles triangle.
Option (3) and Option (5) are the correct options.
Answer:
y = -x -6
Step-by-step explanation:
If we have a slope and a y intercept, we can use slope intercept form
y = mx +b , where m is the slope and b is the y intercept
y = -1x -6
y = -x -6
Its 1/5.
Parallel lines have the same slope.
Hope this helps.
