A triangle’s angles are equivalent to 180 degrees so the third angle would have to equal 20 degrees
Explanation:
step 1. let called the acute angles inside the triangle <1 and <2.
step 2. <2 +140 = 180 (supplementary angle)
step 3. <2 = 40°
step 4. <1 + <2 + 90 = 180. (interior angles of a triangle = 180°)
step 5. <1 + 40 = 90
step 6. <1 = 50°
Herbivores will have less to eat cause more to die off which in turn effects the the predators who eat such herbivores will also have less to eat in the both are be effected negatively
