The angle supplementary to x and 3x are equal.
Supplementary angles = 180
Solution
x + 3x = 180
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
The angle supplementary to x is 3x
3x = 3*45
3x = 135
This angle is vertically opposite y. Vertically opposite angles are equal. So y = 135
Answer
x = 45
y = 135
The length of the enlarged copy in feet is 2.7 feet.
<u>Step-by-step explanation</u>:
- The painting is 4 inches wide and 2 feet long.
- convert inches into feet (1 inch=0.083 foot). Therefore, 4 inches=0.3 feet
- The enlarged copy is 1 foot wide and 'x' feet long.
The width is enlarged from 0.3 to 1 which is increased by 0.7 feet.
∴ The length should also be increased by 0.7 feet = 2+0.7 = 2.7 feet
Answer:
x=22/7 y=4/7 z=-3/7
