Answer:
26°
Step-by-step explanation:
An obtuse triangle is a triangle that has one obtuse angle. Obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees.
An isosceles triangle is a triangle that has two equal sides and angles.
Therefore, an obtuse isosceles triangle is a triangle with an obtuse angle and two equal sides that have two equal acute angles (angle less than 90° ).
Given:
The three angles of the triangle are given to be x°, x° and (10x−2) = 128°. The obtuse angle is 128°, the two x° are acute angles. We are not using equation 10x − 2 since the value of the obtuse angle has been given as 128°
The sum of angles in a triangle is 180°
∴ x° + x° + 128° = 180°
2x° = 180° - 128°
2x° = 52°
x° = 52° / 2
x° = 26°
The measurement of one of the acute angles is 26°
Answer:
x = 13
Step-by-step explanation:
1765
x = 100 (9) + (7) 50 + (19) 20 + (7) 10 - 1765
x = 900 + 350 + 380 + 70 - 1765
x = 1700 - 1765
x = -65
65/5 = 13
x = 13
The highest exponent is 3, so the degree is 3
There are three terms so it is a trinomial.
Problem 1 is asking "the other cost."
It is described in the problem statement as "a cost for every one-tenth of a mile traveled." It is described in the table header as "Mileage Cost in Dollars."
The only value in the "Mileage Cost in Dollars" column is 1, which corresponds to a distance of 1/10 mile. So, it appears the numerical value of "the other cost" is $1 for each tenth-mile traveled.
___
The problem statement does not make clear whether the desired answer is the description of the other cost, or its numerical value.
Answer:
Step-by-step explanation:
The area of the triangle is 4.5
Do 3 times 3 divided by 2 to get the area of triangle.
The area of the rectangle is 24
Do 8 times 3 to get the area of the rectangle.
