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!

We have been given that length of PQ and QR is 25 cm and 8 cm respectively.
We can find possible side length of PR in order to form a triangle using triangle inequality theorem.
Triangle inequality theorem states that the sum of lengths of two sides of a triangle must be greater than length of third side of triangle.
The length of PR should be either less than sum of PQ and QR or greater than difference of PQ and QR.
Let us find the other possible length of PR.
Therefore, the length of PR should be either less than 33 or greater than 17 so that PQ, QR and PR can form a triangle.
Answer:run:83.43 miles
Walk:39.11 miles
Step-by-step explanation:
There are 52.143 weeks in a year;
So each week she runs 1.6 miles=1.6*52.143=83.43 miles
Walks 0.75 miles=0.75*52.143=39.11 miles
