Answer:12cm
Step-by-step explanation:
The ratio are:
4:6:9
Perimeter=57cm
Let a be the unknown value.
The triangle has three sides: 4a, 6a, 9a
Perimeter=The sum of three sides
57=4a + 6a +9a
57=19a
Divide both side by 19
a=57/19
a=3
Therefore
4a:6a:9a
4×3:6×3:9×3
12:18:27
So the shortest side is 12cm
Answer:
Q=4
Step-by-step explanation:
REMOVE PERENTHESES
-4q = 4 x -4
CANCEL -4 ON BOTH SIDES
Q=4
Answer:x=1 y=2
Step-by-step explanation:
you add and get 8x=8 x=1 so plugging in one you get 5+2y=9 so 4=2y so y=2
Remember: Standard formula
a x 10^b
you have shown that 2 angles and the corresponding side are congruent. That is what we would write in the UK
In the US i think its ASA?
