Answer: 50 degrees
Step-by-step explanation:
The exterior is the sum of the interior remote angles.
Answer:
A. ∠ QPR = 17°
Step-by-step explanation:
From the given information, let QP be the length of the ramp.
Then, ∠ QPR is the angle between the ramp and the ground.
∠ PQR is the angle between the ramp and the doorpost and
∠ QRP is the angle between the doorpost and the ground.
Clearly, ∠ PQR = 73° (given)
∠ QRP = 90° (since doorpost and the ground are perpendicular to each other)
Now, use triangle sum propoerty of ΔQPR, we get,
∠ QPR + ∠ PQR + ∠ QRP = 180°
∠ QPR + 73 + 90 = 180°
∠ QPR + 163 = 180°
∠ QPR = 180 - 163
∠ QPR = 17°
I am sure u have to separate the number with their variables so (4x) (2y -y ) (40+10)
Remember that you have to remove the brackets and u should have 4x - 1y + 50 then 4\4 and 50/4 = four cancles out 4 so we have 1y + 12.5 divide each by one one cancles out 1 = 12.5 round it up to 13 but I suggest u check this with anyone else you can but if my math is correct it should be the closest answer
Answer:
There is 25 1/8 inches left
Step-by-step explanation:
We have a board that is 38 3/4 inches
We cut away 13 1/4
38 3/4
-13 1/4
-----------
25 2/4
The saw takes 3/8
25 2/4
- 3/8
-------------
Get a common denominator of 8 2/4 * 2/2 = 4/8
25 4/8
- 3/8
-------------
25 1/8
There is 25 1/8 inches left
