Answer:
145 degrees (c)
Step-by-step explanation:
Take your smallest interior angle (35 degrees) & subtract it from 180.
That will give you your largest exterior angle.
180 - 35 = 145 degrees

Answer:$0.85
Step-by-step explanation:
.95x17= 16.15 17.00-16.15=0.85
This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
