D = s-14
d+s = 76
• substitution;
(s-14)+s = 76
2s-14= 76
2s = 90
s = 45 years old for Sydney
d = s-14 = 31 years old for Devaughn
hope this helps
X = (0 + 8)/2 = 4
<span>y = (0 + 4)/2 = 2 </span>
<span>so midpoint is (4, 2) </span>
we solved it by using mid point formulae
Answer:
Step-by-step explanation:
We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.
, where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,
a = 17, b = 15 and C = 35 degrees. Filling in:

Do that on your calculator in degree mode and you'll find the area to be
73.1 meters squared
The answer is 108 .......
