Step-by-step explanation:

ANSWER

ANSWERIn equilateral triangle ABC,

ANSWERIn equilateral triangle ABC,AD⊥BC

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cm

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABD

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,BE2=DE2+BD2

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,BE2=DE2+BD2BE2=(2108)2+62

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,BE2=DE2+BD2BE2=(2108)2+62BE2=4108+36

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,BE2=DE2+BD2BE2=(2108)2+62BE2=4108+36BE2=63

ANSWERIn equilateral triangle ABC,AD⊥BCSince, it is an equilateral triangle, hence, D is the mid point of BC.BD=6 cmNow, In △ABDAB2=BD2+AD2122=62+AD2AD=108Now, E is the mid point of AD. Hence, DE=2108In triangle BED,BE2=DE2+BD2BE2=(2108)2+62BE2=4108+36BE2=63BE=63
