Answer:
115 degrees
Step-by-step explanation:
for all triangles, the sum of all their angles is 180 degrees so...
180-40-25=115
so the third angle is 115
Answer:
<em>Arielle has 374 grasshoppers and 187 crickets</em>
Step-by-step explanation:
Let's set:
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, thus:
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, thus:
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying:
3y = 561
Dividing by 3:
y = 561/3
y = 187
From [2]:
x = 2*187 = 374
x = 374
Arielle has 374 grasshoppers and 187 crickets
