If both side are the same then the angles are the same. Now knowing that the sym of a triangle is 180 degrees then we can now subtract 38 to get 142 and then divide 142 by 2 which is 71 so that means each of the other two angles is 71 degrees and your answer is A.
Hope this helpsssss

The sum of the measures of the angles of a triangle is 180 degrees.
An isosceles triangle has two congruent sides.
The angles opposite the congruent sides are congruent.
Just like the bottom left angle measures x, the bottom right angle also measures x.

x + x + 38 = 180

2x + 38 = 180

2x = 142

x = 71

So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24

hodyreva [135]

Answer:

(14n - 42)*pi

Step-by-step explanation:

Circumference is 2 * pi * r. Since r in this case is 7n - 21, you can multiply r by 2 and pi, giving you (14n - 42)*pi

Miles is planning to spend 2/3 as many hours bicycling this week as he did last week. Is Miles going to spend more hours or fewe
Taya2010 [7]

Answer:

Fewer hours

Step-by-step explanation:

2/3 is a fraction and shows the parts of a whole. This means that 2/3 of last week is fewer than last week. Last week is the whole for example 15 hours. This week will be 2/3 or 2/3*15 = 10 hours. This week will be less than last week.
