Do you have a specific question we could solve?
Altitude = 90* Angle
15^2+b^2 = 39^2
225+b^2 = 1521
1296 = b^2
36= b
15^2 + b^2 = 17^2
225 +b^2 = 289
64 = b^2
8 = b
36 + 8 = 44
39+17 = 56
56 is greater then 44
Triangle Inequality Theorem Proves
So QR = 44
D.
10>(12)-7(0)
10>12.... False
C. 145°
Explanation:
angles A and D are opposite adjacent.
Answer:
60 degrees
Step-by-step explanation:
First we need to know how many degrees are in a parallelogram. We can use the formula 180(n-2) (n is the number of sides)
This works out to 180(4-2)=360 degrees.
Now we can set up the following equation as:
2(120)+2x=360 Subtract 240 from both sides to get:
2x=120 Divide by 2 to get:
x=60 degrees
Therefore we know 2 angles are each 120 degrees and the other 2 are 60 degrees.
Makes sense?
