An isosceles triangle has an angle that measures 40 degrees. 70 and 100 are other angles could be in that isosceles triangle
Solution:
Given that isosceles triangle has an angle that measures 40 degrees.
If a triangle is isosceles then it has 2 identical angles and the third different one.
Let the two identical angles be "a"
We know that sum of angles in a triangle is 180 degree
a + a+ 40 = 180
2a + 40 = 180
2a = 180-40
a = 70
Thus the two identical angles are 70 degree and 70 degree
Now let the identical two angles be "40" and the third angle be "a"
Now sum of angles = 180 degree
40 + 40 + a = 180
80 + a = 180
a = 100
Thus the third angle in this case is 100
70 and 100 are other angles could be in that isosceles triangle
Answer:
70, 40, and 100
Step-by-step explanation:
I am taking the IXL and wanted to know what t was and i got it wrong because someone answered it was only 70 and 100 when it is actually 40 100, and 70. Trust me i just got it wrong and IXL gave me the right answers.
