The angles 131°; 160° and n° are the exterior angles of the triangle.
The sum of measure of an exterior angles of the triangle is equal 360°.
Therefore we have the equation:
Answer: A. 69°
Answer:
is that all?
Step-by-step explanation:
Answer: Matt has 42 marbles and Maya has 48 marbles.
Step-by-step explanation:
Matt's has more than 41, but less than 43 marbles. Since each marble has to correspond to a whole and real number, the only number between 41 and 43 is 42. Likewise the only number between 47 and 49 is 48 since Maya has more than 47 marbles but less than 49 marbles.
Answer:
x = 10
Step-by-step explanation:
If you add the angles up, you get 110, so the missing angle is 70. It is an isosceles triangle. The bottom length should be about 11.
