31 degrees, 31 degrees, 118 degrees
Step-by-step explanation:
Step 1 :
Let x be the measure of 2 angles of the given isosceles triangle with same measure
Let y be the measure of 3rd angle
So we have x + x + y = 180
Step 2 :
Given that the measure of 3rd angle of triangle is 25° more than three times the measure of either of the other two angles
So we have , y = 3 x + 25
Step 3:
Substituting for y in the first equation we have,
x + x + 3 x + 25 = 180
=> 5 x + 25 = 180
=> 5 x = 180-25 = 155
=> x = 155/5 = 31
Hence the 2 angles of the triangle are 31 degrees.
Step 4:
we have y = 3 x + 25
=> y = 3 * 31 + 25 = 118
Hence the 3rd angle of given triangle is 118 degrees

The answer to this question is -11/12.. l hope it helped??
Step-by-step explanation:
-2x,7x and 2x,x3
look for the same variables or look if they both have a negative or a positive without a variable , example: -2.345 has the same terms as -5.99
Given:
Steven wrote this equation:
To find:
The error in Steven's reasoning and then find the correct product.
Solution:
We have,
This statement is incorrect because we cannot write product directly as Steven wrote.
We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.
Therefore, the correct product is 72.
