Hello!
The area of a triangle is always 180°
And we know that angle "A" is 90°
So we can do 180 - 90 = 90
Which means that.
(2x+14) + (4x-26) = 90
You combine like terms
6x - 12 = 90
add 12 to each side.
6x = 102
divide by 6 on both sides
x = 17
So the answer is 17°
Hope this helps!

Answer:
8
Step-by-step explanation:
72/s
Let s=9
72/9 = 8
The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.
Error = 1/2(Maximum range - Minimum range) = 1/2(3.2-1.1) = % = 0.0105
If p is the point estimator;
Then,
Minimum range = p - Error
Maximum range = p + Error
Solving one of the two expressions,
0.011 = p - 0.0105 => p = 0.011+0.0105 = 0.0215 = 2.15%
