Answer:
angle Z=20°
side xy≈15.36
hypotenuse≈19.49
Step-by-step explanation:
Find angle z adding the other two angles and subtracting that by 180 to get 20.
(12)tan(20) gets you side xy which is 15.36
12^2+15.36^2=xz^2
Answer:
-and a -= a positive
Step-by-step explanation:
-8+-9=19
Answer:
396
Step-by-step explanation:
15x6= 90,Therefore you found one side, now you need to multiply by 4 because their is 4 sides.
90x4= 360
6x6=36
Add them all together, 360+36= 396.
I assume that the answer the number 13 is that he applied the principle incorrectly.
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!
