Answer:
The answer is option A.
<h2>50 degrees</h2>
Step-by-step explanation:
To find angle C we use the cosine rule
That's
AB² = AC ² + CB ² - 2(AC)(CB)cos C
AC = 7.5
AB = 6
CB = 6.5
6² = 7.5² + 6.5² - 2(7.5)(6.5)cosC
36 = 56.25 + 42.25 - 97.5cos C
36 - 98.5 = - 97.5 cos C
-62.5 = - 97.5 cos C
cos C = -62.5 / - 97.5
C = cos ^-1 25/39
C = 50.1
The final answer is
<h3>C = 50°</h3>
Hope this helps you.
it’s 60 cm^2 because you multiply base times height then divide by 2.

Subtract 5 on both sides to cancel out the positive 5 and to get the variable x on one side alone.
Final Answer: x= 11</span>
27.8 X 9.6= 266.88
rounding off we get 267
Answer: To find the vertex: use formula x= -b/2a.
plug x into the given equation to find y value.
now you have (h,k)
find a point on the graph and plug in to the vertex form equation to find "a"
