Question

one of the equal angles of an isosceles triangle is 75 Celsius find the other two angles ​

Answer 1

Step-by-step explanation:

in an isosceles triangle two sides are equal

if one isosceles side is 75 degree then other side will also be same = 75 degree

sum of triangle = 180 degree

two sides are equal to =75 °

then

let the 3rd side be x

therefore

180 = 75 + 75 +x

x=180-150

x=30° Ans

Answer 2

Answer:

Measure of other two angles of isosceles triangle are $75^{0}$ and $30^{0}$.

Step-by-step explanation:

Given : One of the angles of isosceles triangle = $75^{0}$

To find : Measure of other two angles =?

Solution :

• It is given that measure of one of the angles of isosceles triangle = $75^{0}$
• We have to find the measure of other two angles.
• We know that, isosceles triangle is the triangle who has two equal sides and the angles opposite to equal sides are also equal.
• From the given data, measure of one of the angles of isosceles triangle = $75^{0}$.

• ∴ Measure of other angle will be equal to $75^{0}$.
• We know that,  sum of all angles of a triangle is $180^{0}$.
• The equation becomes,

            $75^{0} +75^{0} +$ Third angle = $180^{0}$

                ∴ $150^{0}+$ Third angle = $180^{0}$

                        ∴  Third angle = $180^{0} -150^{0}$

                        ∴  Third angle = $30^{0}$

• ∴  Measure of other two angles of isosceles triangle are $75^{0}$ and $30^{0}$.
