Answer:
x = 
, y = 2
Step-by-step explanation:
using the tangent ratio and the exact value tan45° = 1 , then
tan45° = 
= 
= 1 , then
x =
----------------------------------
using the cosine ratio in the right triangle and the exact value
cos45° = 
, then
cos45° = 
= 
= ( cross- multiply )
y = × 
= 
= 2
Answer:
?
Step-by-step explanation:
You can’t know that, because you don’t know how many total apples there are.
Answer: 160 inches.
Step-by-step explanation:
If an octagon has 8 sides and the side length is 20 inches, 20 x 8 = 160 inches. That means she needs 160 inches of wire.
Alice has read 150 pages, you would multiple 200 by .75 (75%). If Nina had read 50% of her book and she read 150, you multiple by 2, and get 300. So Nina has 300 pages in her book.
<span>To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y -intercept--this should be of the form (0, b) . ... Therefore, the equation for this line is y = - x + 2 .</span>
