An isosceles triangle has two angles that are each 57. Find the measure of the third angle

The third angle measures 66°

Step-by-step explanation:

If we look at the properties of triangles, we will know that all triangles have angles that, when added together, equal 180 degrees. Because we already know the measurement of two of the angles, all we have to do is add them up and subtract the sum by 180.

57+57=114

180-114=66

We got 66 as the measure of the last angle. Now, to make sure we have the right answer, we are going to check our work. We do this by adding together all of the angle measurements. If they all add up to 180, then we know we have the correct answer.

57+57+66=180

We were correct! Now we have the measurements of all three of the triangle's angles. Great job!

I hope this is easy to understand. Please let me know if you need any more help. Have a great morning!

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
