first find the unknown angle, 180o - (62o+62o) = 56o next use the law of sines to find the other side: sin 62o / 15cm = sin 56o / X Solving for x, X = 14.08 cm

What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
What degrees are each corner in an isosceles triangle?
The sum of the interior angles of a triangle is 180o. In an isosceles triangle two of the angles are the same, say x. The third angle is then 180o-2x.
If two angles of a triangle each measure 70 degrees what is the triangle is described as?
That's an isosceles triangle.
What is the angle that is not congruent to the base angles of an isosceles triangle?
The sum of the internal angles of a triangle is 180 degrees. If you know the size of the angles at the base of an isosceles triangle, the final angle can be found by subtracting the size of the two known angles from 180.
Angles of isoceles triangle?
The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is about an isosceles triangle, not an equilateral triangle. The angles of an isosceles triangle are x, x and 180-2x degree where x is a measure between 0 and 90 degrees.
What degree angles has an isosceles triangle?
a isosceles has 180 degrees
What is the degrees of an isosceles triangle?
An isosceles triangle has 3 interior angles that add up to 180 degrees, and 2 of its angles are equal and two of its sides are equal.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
Which triangle is not an isosceles triangle?
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle with angles of size (90, 45, 45) degrees is a right angled isosceles triangle.
What angles does an isosceles triangle have?
-- In any triangle, the three inside angles always add up to 180 degrees. -- In an isosceles triangle, two of the three inside angles are equal.
How many angles are there in an isosceles triangle?
There are 3 angles in an isosceles triangle and 2 of them are equal in size. The 3 interior angles add up to 180 degrees.
What type of triangle has angles of 75 75 and 30 degrees?
An isosceles triangle has angles of 75, 75 and 30 degrees.
Does an isosceles triangle have a angle greater than 90?
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees. You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.
Is is possible for an isosceles triangle to be an acute triangle?
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
What is the maximum vertex angle in an isosceles triangle?
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
What is an isosceles triangle measure up to?
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
