Answer:
ΔDCE by ASA
Step-by-step explanation:
The marks on the diagram show AE ≅ DE. We know vertical angles AEB and DEC are congruent, and we know alternate interior angles BAE and CDE are congruent. The congruent angles we have identified are on either end of the congruent segment, so the ASA theorem applies.
Matching corresponding vertices, we can declare ΔABE ≅ ΔDCE.
Answer:
26m
Step-by-step explanation:
The value of the opposite side (height of the flagpole) is to be determined given the angle and the value of the adjacent side(horizontal distance )
We would use tan 18 to determine the value of the missing side
tan 18 = opposite / adjacent
0.3249 = opposite / 80
0.3249 x 80 = 26m
please find attached a graphical interpretation of this question
Complete the square by using the following form:


The vertex is at (3,7)
The squared term is positive so it opens up and vertex is a minimum.
0.035 is less than 0.04. When you look at their hundredth digit, you can see that 3 is less than 4.
