Answer:
a) 0
b) scalene and obtuse
Step-by-step explanation:
∠A = 20
∠B = 60
∠C = 180 - 20 - 60 = 100 (obtuse)
Since none of the angles are equal, no sides are equal either
So, it's a scalene triangle
Since one angle is obtuse, it's an obtuse triangle
Answer:
f(a + 2) = (5 + a) / (a - 1)
Step-by-step explanation:
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
64 is the answer because it’s 8 for one And 8*8=64
