Answer:
a) a + c = 90
d) a + b + c + 30 = 180
e) The angles marked a and b are vertical
f) The angles marked a and c are complementary.
Step-by-step explanation:
A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.
Hope this helps! Have a wonderful rest of your day!

-31x+5 is the same as (-18x-12)-13x+17
Answer:
I think that you have to multiply the angles with each other and thats how you get your answer. Can I get Branliest?

Answer:
Isosceles and obtuse
Step-by-step explanation:
It is not a scalene triangle because it has two same lengths 41 degrees and 41 degrees.
<u>It is a </u>Isosceles triangle because two of the sides have the same lengths 41 degrees and 41 degrees
<u>It is an</u> obtuse triangle because it has on obtuse angle which is 98 and two acute angles that are 41 degrees
It is not an equilateral because not all of the sides are the same lengths
It is not a right triangle because there are 90 degree angles
It is not an acute triangle because not all the angles are acute angles
