Remark
The point value is (-2,5) So we know the two sides. We need the hypotenuse. We should notice that the x value is minus (-2) and value is y value is plus (5). That means we are in quad 2. Be careful how you read that. (-2,5) is a point. It is not a tangent.
Step One
Find the hypotenuse.
a = - 2
b = 5
c = ??
c^2 = a^2 + b^2
c^2 = (-2)^2 + 5^2
c^2 = 4 + 25
c^2 = 29 Take the square root of both sides.
sqrt(c^2) = sqrt(29)
c = sqrt(29)
Step Two
Find the Cosine of the angle.
Cosine(theta) = adjacent / hypotenuse
Cosine(theta) = -2 / sqrt(29) <<<<<<< Answer
Again, watch out for what you are given.
Answer:
The answer is 15 21/40
Step-by-step explanation:
If you convert 8 1/8 to 8 5/40 then convert
7 2/5 to 7 16/40 then add the wholes 7 + 8 = 15
and then add the actual fractions 5/40 + 16/40 = 21/40
then add the whole and the fraction 15 + 21/40 youll end
up with 15 21/40 so that is the awnser PS I’m in 5th grade age 10
This looks hard... good luck ! :D
