What is the measure of each base angle of an isosceles triangle if its vertex angle measures 40 degrees and its 2 congruent sides measure 25 units?
Length of sides is irrelevant. Angles are ((180 - 40)/2) ie 70o
What is an 8 unit protractor?
A protractor that can be made from a square piece of tracing paper or wax paper to make an angle measurer. It is divided into 8 equal units. The units are labelled from 0 to 7 clockwise and counterclockwise. To measure an angle, count how many units fit the angle
If angle A is 60 degrees angle B is 45 degrees angle C is 75 degrees and the length of side AC is 10 units then what is the length of side AB?
This problem can be solved using the Sine Rule :a/sin A = b/sin B = c/sin C 10/sin 45 = AB/sin 75 : AB = 10sin 75 ÷ sin 45 = 13.66 units (2dp)
What is a 80 percent grade?
This means that for every 100 units of distance forward, you go 80 units up. (you have to go about 128.06 along the slope to do this) This is an angle of 38.66 degrees.
How do you find the hypotenuse of a triangle without Pythagoras theroem?
You need a side and another angle. Hypo = side / sin angle. Eg if a side is 6 units and an angle 30 degrees then hypotenuse = 6/0.5 = 12
What is a unit used to measure an angle?
A degree is the measure of an angle.
What is the measure of the vertex angle of an isosceles triangle if the measure of one of it's base angles is 56?
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
What is the unit of measure for an angle?
Arc degrees, minutes and seconds are the units of angular measurement.
What is a Angle unit of measure?
Angles are units of measure that define the relationships between two intersecting lines It's tough to demonstrate by text, but I'm goind to give it a try; _\ = an angle of about 60 degrees _/ = an angle of about 120 degrees _| = an angle of 90 degrees (also called a 'right' angle) _._ = an angle of about 180 degrees = is an angle of about 0 degrees
What is the measure of an arc on an angle that is 84 degrees?
84*r*pi/180 units of length where the radius is r units of length.
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and the two congruent sides each measure 21 units?
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
Abcd is a parallelogram if ad equals 10 units ab equals 8 units ac equals 12 units ed equal4.5 units and if angle aed equal 100 degrees what is the measure of angle bec?
As we read the question, we sketched it out here on our yellow pad. We got 100 degrees for angle 'bec', but we have no confidence in that result, because we're not at all sure that our sketch is the only possible one that fits the details in the question. We're pretty sure that this is another case where we really need to see the labeled drawing described in the question before we can tease out any reliable answer.
What do radians and degrees have in common?
They are both units in the measure of an angle. There are 360 degrees in a full turn of a circle. There are 2 pi (radian measure) in a full turn of a circle.
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is the measure of the base angle of an isosceles triangle if the measure of the vertex angle is 42 degrees and the two congruent sides each measure 21 units?
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
What is the measure of each base angle of an isosceles triangle if its vertex angle measure 36 degrees and its 2 congruent sides measure 13 units?
If the vertex angle measures 36 degrees, then each base angle is 72 degrees, regardless of the length of the congruent sides. They may be the length of a DNA strand, a 57 Chevy, or the distance to the Andromeda Galaxy. It doesn't matter. The base angles are still 72 degrees.
What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38 and each of the two congruent sides measures 21 units?
Each of the base angles measure 71 degrees
