Question

A А
36
B
Fig. 11.35
gure 11.35, ABCDE is a regular pentagon. If EBD = 36. find 1.2 and 3​

Answer 1

Answer:

<1=108

<2=<3=36°

Step-by-step explanation:

sum of all angles of pentagon=n-2X180

=5-2X180

=3X180

=540°

an angle = 540/5

=108°

<1=108°

in ∆ AEB,

AE=AB. (REGULAR PENTAGON)

<ABE=<2. (side opposite to equal side are equal)

108°+<ABE+<2=180°

2x=72

x=36

<2=36°

<36+<36+<3=108°

<3=108-72

<3=36
