Answer:
d = 52
Step-by-step explanation:
The two angles form a straight line so they are supplementary
Supplementary angles add to 180
d+128 = 180
Subtract 128 from each side
d+128-128 = 180-128
d = 52
Answer:
1 inch: 4 ft
Step-by-step explanation:
We can use proportions to solve this problem. Put the blue print size on the top and the real life size on the bottom.
1/4 inch 1 inch
----------- = -------------
1 ft x ft
Using cross products
1/4 * x = 1*1
Multiply each side by 4
4 * 1/4 *x = 4*1
x =4
1 inch: 4 ft
Answer:
19/20
Step-by-step explanation:
