Answer:
Both triangles are scalene & Both triangles have an obtuse angle.
Step-by-step explanation:
<u>Key skills needed: Triangle recognition, Comparing Triangles</u>
1) We are given those 2 triangles, and we need to see if they are isosceles, scalene, obtuse, and acute.
2) To get this, let's define each thing:
Acute triangle - Means that all the angles in triangle are acute, which means they are less than 90 degrees in measure.
Obtuse triangle - Means that one angle in the triangle is obtuse, which means it is greater than 90 degrees in measure.
Scalene triangle - All the sides of the triangle are different in size/length
Isosceles triangle - 2 sides of the triangle are the same length
3) Now, we can use this to see what both triangles are:
--> Both triangles are not isosceles, they are both scalene. This is because all the sides of each triangle are different in size/length. This makes it scalene.
--> Both triangles are not acute triangles, they are both obtuse triangles. This is since the largest angle in each triangle is clear an obtuse angle (it looks like it is more than 90 degrees). Refer to the image I post as help.
With the observations above: We can say that both triangles are scalene, and both triangles are obtuse triangles.

Answer:
Step-by-step explanation:
<u>Absolute Value Inequality</u>
Assume the actual width of a safety belt strap for a certain automobile is x. We know the ideal width of the strap is 6 cm. This means the variation from the ideal width is x-6.
Note if x is less than 6, then the variation is negative. We usually don't care about the sign of the variation, just the number. That is why we need to use the absolute value function.
The variation (unsigned) from the ideal width is:
The question requires that the variation is at most 0.45 cm. That poses the inequality:
That is the range of acceptable widths. Let's now solve the inequality.
To solve an inequality for an absolute value less than a positive number N, we write:
This is a double inequality than can be easily solved by adding 6 to all the sides.
Operating:
That is the solution in inequality form. Expressing in interval form:
