I'm very sure the answer would be (4, 64)
Answer:
The First one is an Acute angle 90 degrees
Step-by-step explanation <em>The second one is an Equitateral angle has three equal sides. The third one is an obtuse greater than 90. and the last one is an right angle. has one right side.</em>
That's of course the 30/60/90 right triangle.
If you need to see the algebra, the acute angles in a right triangle are complementary, adding to 90 degrees:
x + 2x = 90
3x = 90
x = 30
Answer:
18x+20y≤ 230
Step-by-step explanation:
step one
given data
A black sweatshirt costs $18, and a white sweatshirt costs $20
let x be the number of black and
let y be the number of white sweatshirts
step two:
Also, we are told that the club plans to spend no more than $230
hence the inequality for the situation is
18x+20y≤ 230
