The ratio of the angle maeasures in a triangle is 5 4 1 draw and classify the triangle by its angle measurements?
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
What is the measure of the third angle in a triangle if the other two angles measure 18 and 67?
The third angle is 95 degrees because 180-18-67 = 95
2 suppplementary angles have measures in the ratio 3and7?
If the angles are 3x and 7x their sum, 10x is 180 degrees. So x = 18 and so the angles are 18*3 = 54 degrees and 18*7 = 126 degrees.
What is the sum of the measures in degrees of the interior angles of an 18-sided polygon?
(18-2)*180 = 2880 degrees
What is the sum of the measures in degrees of the interior angles of an 18 sided polygon?
(18-2)*180 = 2880 degrees
A triangle has angle measurements of 37°, 85°, and 58°. What kind of triangle is it?
Obtuse scalene triangle ,these three angles greater than 90 degrees but less than 18 degrees
The ratio of the angle maeasures in a triangle is 5 4 1 draw and classify the triangle by its angle measurements?
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
What are the opposite angles in a triangle to its sides of 22cm and 62cm and 48cm?
Using the cosine rule in trigonometry the opposite angles to the given dimensions are 17.9 degrees, 120 degrees and 42.1 degrees respectively.
What is the measure of the third angle in a triangle if the other two angles measure 18 and 67?
The third angle is 95 degrees because 180-18-67 = 95
What are a score or more facts about the properties of angles and triangles?

How many sides does a regular polygon have if its interior angles are 162 degrees each?
A twenty-sided polygon is called an "icosagon." If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the center from each angle.. There will be 20 small angles arranged in a circle around the center. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.

What is the sum of the degrees of the interior angles of an 18 gon?
(18-2)*180 = 2880 degrees
Ratio of the angles in a triangle?
if the angle of a triangle are in the ratio 7:11:18,find the angle
A base angle of an isosceles triangle is 9 degrees more than the vertex angle Find the vertex angle?
let the vertex angle be x degrees, then the base angle is x + 9 degrees. Since in a triangle the sum of the angle is 180 degrees, and the base angles in an isosceles triangle are congruent, we have: x + 2(x + 9) = 180 x + 2x + 18 = 180 3x + 18 = 180 subtract 18 to both sides 3x = 162 divide by 3 to both sides x = 54 Thus the vertex angle is 54 degrees.
If the sum of the interior angles of a regular polygon is 2880 degrees how many sides does this polygon have?
18 Angles on a straight line = 180 degrees interior angles 2880 + exterior angles 360 = 3240 degrees 3240 divided by 180 = 18 sides Note that the exterior sum of angles of any polygon is always 360 degrees.
