Answer: angle two us the same as angle 4,6,and 8
angle 1,3,5, and 7 are 70
Step-by-step explanation:
Answer:
a) x = 260
b) g = 218
c) z = 30
d) h = 5
Step-by-step explanation:
a)
Predict a number; let's say x = 225
Too low; try with a higher number; let's say x = 270
Too high, we're closer.
x = 260
--------------------------------------------------------------------------------------
b)
let's say g = 230
Too high. Try g = 221
We're almost there. Let's try with g = 218
----------------------------------------------------------------------------------------
c)
Let's try with z = 15
Too low; try a higher number. z = 30
--------------------------------------------------------------------------------------------
d)
Let's try with h = 6
Too high; let's try with h = 5
Answer:
60.2 grams
Step-by-step explanation:
a = 510(1 - .263)⁷
a = 60.2341229517
rounded
a = 60.2 grams
I see the cosine in problem 7 and I see the cotangent in problem eight. So I know that you're talking about trig functions in class. Problem 9 is trying to find out if you know what they're good for. You have a right triangle and you know the lengths of all three sides. So you can easily find the sine or the cosine or the tangent or the cotangent of the angle. Pick one and calculate the number. Then use your calculator to find the angle that has that number for the trig function that you chose.
