Answer:
- C. length = 23 cm; width = 7 cm
Step-by-step explanation:
<u>Let the width is x, then the length is:</u>
<u>Perimeter is:</u>
- P = 2(l + w)
- 60 = 2(x + 2x + 9)
- 30 = 3x + 9
- 3x = 21
- x = 7
<u>Dimensions are:</u>
- Width = 7 cm, length = 2*7 + 9 = 23 cm
Correct choice is C
Answer:
A, n = (8 - 7p)/m.
Step-by-step explanation:
mn + 7p = 8
mn = 8 - 7p
n = (8 - 7p)/m.
Answer:
Step-by-step explanation:
A triangle adds up to 180.
180 - 50 = 130
Since both of the missing angles are congruent each of the missing angles is 65 degrees.
130/2 = 65
As per the exterior angle theorem, the measure of the exterior angle is determined by the sum of the opposite interior angles.
65 + 65 = 130
So, the measure of
