Answer: C. Obtuse
Step-by-step explanation:
It is an obtuse triangle because one angle (the one which measures 110 degrees) is obtuse - it's greater than 90 degrees.
Since, it is given that angle A is a right angle and angle B is a right angle.
We have to prove that 
Now, we have to complete the given statement.
It is given that
and
are right angles. This means that
and
because of the definition of the right angles. By the substitution property of equality
.
5B + B = 20
6B = 20
B = 20 / 6
= 10/ 3 hrs
A = 5 ( 10/3 + 2)
= 5 (16/3)
= 80 / 3 hrs
Brian traveled 10/3 hours and Annie traveled 80/3 hours.
Answer:

Step-by-step explanation:
1¼ feet = 1.25 × 12 = 15 inches
15 + 8 = 23 inches
X = 2
4x + 8 = 16
