Answer:
15.20feet
Step-by-step explanation:
Length of the ladder = 16foot (hypotenuse)
BAse of the ladder from the house = 5feet (adjacent)
height of the house = x (opposite)
Using the pythagoras theorem
hyp^2 = opp^2 + adj^2
16^2 = 5^2 + opp^2
256 = 25 + opp^2
opp^2 = 256-25
opp^2 = 231
opp =√231
opp = 15.20
Hence the house is 15.20feet high up the house
Answer:
9 gal
Step-by-step explanation:
Answer:
D. x= 28, 2=23; Use corresponding and supplementary angles.
Step-by-step explanation:
The degrees of (5y-4)° and 3y° both (added together) sum up to 180 degrees.
So the equation would be: (5y-4)+3y= 180.
Step 1- Add common variables.
(5y+3y)-4= 180
8y-4= 180
Step 2- Add 4 to both sides.
8y-4= 180
<u> +4 +4</u>
8y= 184
Step 3- Divide both sides by 8.
<u>8y</u>= <u>184</u>
8 8
y= 23
Now that we know what the variable y equals to, we can now solve for x. The equation would be: 3y=(2x+13).
Step 1- Substitute the known variable.
3(23)=2x+13
69= 2x+13
Step 2- Subtract 13 to both sides.
69= 2x+13
<u>-13 -13</u>
56= 2x
Step 3- Divide both sides by 2.
<u>56</u>= <u>2x</u>
2 2
x= 28
Hope this helps! :)
Since 1 kilometer is equal to 1000 meters, Derek road 7 kilometers everyday. For a all 3 days, you would do 7 x 3 which is 21. In 3 days, Derek road 21 kilometers.
