Answer:
∠ XYZ ≈ 66.4°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosY = = = , then
∠ Y = ( ) ≈ 66.4° ( to 1 dec. place )
Answer:
<h2><u><em>
5 and 7</em></u></h2>
Step-by-step explanation:
One number is 2 more than another. The difference between their squares is 24. What are the numbers?
(x + 2)² - x² = 24
x² + 4x + 4 - x² = 24
4x + 4 = 24
4x = 20
x = 20 : 4
x = 5
----------------------
5 + 2 = 7
check
(5 + 2)² - 5² = 24
49 - 25 = 24
24 = 24
the answer is good
X = 90 degreees, so you take 47 and 90 add them together and you get 137 degrees. you need 180 to make a triangle, so you subtract 137 from 180. the answer for y is 43 degrees. hope that helps
