Answer:
d, 3 5/8
Step-by-step explanation:
Answer:
b and d
Step-by-step explanation:
b and d from the picture
same angle of 25 between sides with 1:2 side to base ratio
X=total number of pages.
1)we calculate the total number of pages.
32% of x =80
(32/100)x=80
x=(80*100)/32
x=250.
2) we calculate the number of pages don´t read.
number of pages don´t read=250-80=170
Answer: 170 pages.
Answer:
6π or 18.84956 (rounded to 18.85)
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Given that ∠A ≅ ∠B, Evelia conjectured that ∠A and ∠B are acute angles.
Consider all options:
A. If m∠A=114° and m∠B=170°, then angles A and B are not congruent, so this is not a counterexample.
B. If m∠A=126° and m∠B=126°, then angles A and B are congruent and both these angles are obtuse (their measures are greater than 90°). This means that two obtuse angles can be congruent, so this is a counterexample. True option.
C. If m∠A=30° and m∠B=40°, then angles A and B are not congruent, so this is not a counterexample.
D. If m∠A=45° and m∠B=45°, then angles A and B are congruent, so this examples show two congruent acute angles. But if we have to prove some statement, we have to prove this statement for an arbitrary angles, not for one pair of angles. Moreover, this is an example illustrating given statement, but is not a counterexample.
