If BD is a bisector, then angles 1 and 2 are equal. Since they’re the only two angles within 56/2 = 28
It’s 25.
-so it’s saying 5/x is the same as 6/30. we have to find X by dividing. The answer to the division is 5. Now take your 5 and multiply it by the 5 in the fraction to get 25.
Answer:
26mm
Step-by-step explanation:
if x=width
7×x=42
x=42÷7
x=6
perimeter = 6+6+7+7=12+14=26mm
Answer:
lacy = 8 jack= 24
Step-by-step explanation:
let x be lacys age
3x - 3 + x-3 = 14
3x+x -3 = 14 + 3 = 17
4x = 17 +3 = 20
x = 20/4 = 5
lacys age now = 5+3 = 8
jacks age now = 8 * 3 = 24
