I believe 30 is the answer :)
Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x
Therefore, the width is 16 cm, the width is 16*3=48 cm
Answer:
67°
Step-by-step explanation:
In order to find the value of x, subtract the sum of the given angles from 180° so:
=180-(53+60)
=180-113
=67°
Always start with what’s in the parentheses:)
