Answer:
A. Actute triangle
Step-by-step explanation:
Is A because an acute triangle is a triangle where all the angles are the same.
Can not be B. because isosceles triangles have two sides that are the same which doesn't relate to angles.
Can not be C. because equilatiral triangles are triangles with sides that are all the same.
Can not be D. because for a triangle to be obtuse one of the angles needs to be greater that 90 degrees.
So it has to be A.
An arithmetic sequence is a sequence of numbers in which the difference between the consecutive terms is constant.
The Answer is B= 17c
62 = 9/5c + 32
62 - 32 = 30
30 / (9/5) = 17
C = 17
