D. obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.
Answer:
pi
Step-by-step explanation:
First find the circumference of a circle with radius 4
C = 2 * pi *r
C = 2*pi*4
C = 8pi
A circle has 360 degrees
Find the fraction of a circle that 45 degrees is
45/360 = 1/8
Multiply the fraction by the circumference
1/8 *8pi = pi
