The triangle is isosceles, so the bottom angles have the same measure. So, the angles measure 2x, 3x+5 and 3x+5.
The sum of the interior angles of a triangle is 180, so we have
So, angle A measures

Answer:122° I think
Step-by-step explanation:
58+58=116
360-116=244
244/2=122°
Answer:
0.41 cm
Step-by-step explanation:
The scale on the map is 1 in 86 mi.
This means that, 1 cm on the map represents 86 miles in real life, or on earth.
Then we're told that in real life, a distance is 35 miles, and how far they are on the map.
If 1 cm equals 86 miles, then we can say that x cm equals 35 miles
1 cm ----> 86
x cm ----> 35
x * 86 = 35 * 1
x = 35 / 86
x = 0.41 cm
Therefore, they must be 0.41 cm farther or closer apart on the map scale.
