There are two equal sides of 10, which means this is an isosceles triangle. With an isosceles triangle, there are also two equal angles (25° each in this case). If angle D equals 25°, then angle F also equals 25°. Subtract angles D and F from the total degrees in a triangle.

Triangles Degrees= 180° total

Find angle E:
= total triangle degrees - < D - < F
= 180° - 25° - 25°
= 130°

ANSWER: Angle E is (B) 130°

Hope this helps! :)

Find the measure of each exterior angle.

devlian [24]

Answer:

The answer is 137 degrees

Step-by-step explanation:

Add up the two angles you know already

93 + 44 = 137

Then you take that number and subtract it from 180 in order to find the other interior angle.

180 - 137 = 43

So angle LKJ is 43 degree

Now to find the exterior angle you take the missing angles measurement

Which is 43 and subtract it from 180 to get 137
