Answer;
7.77
Step-by-step explanation:
A is 4 and b is 63 have a good day
-6-y / 3-7 = -2/3
-6-y / -4 = -2/3
Multiply through by -12:-
3(-6-y) = 8
-18 - 3y = 8
3y = - 26
y = -8 2/3
If we have 156 beads and we can make one bracelet with 9 beads we divide 156 by 9 and get 17 1/3. since we cannot have 1/3 of a bracelet, we can make 17 bracelets.
When any angle bisects with other angle then both the angles are equal.
Then, m of angle ABD = angle CBD
ABD = 70
ABD = CBD = 70°
ABC = 70 + 70 = 140°
