To determine the measure of angle A at the apex of a triangle, you need information about the other angles or the lengths of the sides. In a triangle, the sum of all interior angles is always 180 degrees. If you have the measures of the other two angles, you can simply subtract their sum from 180 degrees to find angle A. If you provide more specific details, I can give a more precise answer.
What else can I help you with?
What is an apex angle?
Apex (Angle)The apex is the pointed tip of a cone. The apex angle is the angle between the lines that define the apex, as shown to the left.
In an isosceles triangle if a base angle has a measure of 43 degrees then the vertex angle must have a measure of 80 degrees as well true or false?
False because if each base angle is 43 degrees then the apex angle must be 94 degrees
What point of an angle is equidistant from the sides of an angle?
Bisector (apex)
What is the relationship between the measure of an angle and the reflex measure of the angle?
they both measure the angle in degrees
Does circles have apex?
Not normally because an apex angle is found on an isosceles triangle.
The shortest side of a triangle is always opposite the angle with the measure?
angle with smallest measure - apex
Which angle in DEF has the largest measure?
NO.
The measure of an angle whose sides overlap is degrees?
0 APEX!!

In RST RS 15 RT 12 and ST 17. Which angle of RST has the smallest measure?
It is angle RST.
Congruent angles must satisfy which of they following conditions?
they have same angle measure - apex
The measure of an exterior angle and the adjacent interior angle sum to 360 degrees because they form a linear pair?
False*APEX*
Should all congruent angles must satisfy which of the following conditions?
no they have the same angle measure APEX
In an isosceles triangle if a base angle has a measure of 43 degrees then the vertex angle must have a measure of 80 degrees as well true or false?
False because if each base angle is 43 degrees then the apex angle must be 94 degrees
In order to apply the law of cosines to find the measure of an interior angle what is enough to know?
The lengths of all three sides of the triangle APEX:)
What is apical angle in cone?
The apex angle is the angle in a cone that the apex, or point, of the cone takes. This is measured from two opposite sides of the cone, which is found by drawing a line from the apex to the center of the circular base, then drawing a plane through this line and using the lines of the plane's intersection of the cone to measure the angle.
If a point is equidistant from the two sides of an angle then it is?
on the perpendicular bisector
