Answer:
12/13
Step-by-step explanation:
we know this is a right triangle, and we know that the hypotenuse is the longest side. so we can already say that the hypotenuse of the triangle is DF or 78.
when you draw it out, you find that the shortest leg is 30 and the second is 72 and the hypotenuse is 78. we also know that cosine is adjacent/hypotenuse. once you draw the triangle and notice which side is adjacent to angle F, just fit it into the formula and you get:
cos F = 72/78
cos F = 12/13
Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
Your answer is quite simple, really. All you have to do is divide $3.36 by 7 (The ounces of grapes he bought), and your answer should come out to be $.48, to check if this is correct, you then should add .48, 7 times, or multiply it by 7. Which, is what I did. And that should bring you to 3.36!
Answer:
1/3
Step-by-step explanation:
A die has 6 numbers 1-6 and there are two numbers higher then 4, 5 and 6. so that is 2/6 or 1/3
