Answer:
John has $21.
Step-by-step explanation:
Let John's "wealth" be w. Then 2w+8 = 50, or 2w = 42, or w = 21.
John has $21. Eight more than twice this is 42+8 = 50, as expected.
Answer:
Approximately 11 feet.
Step-by-step explanation:
Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:
= 
+ 
- 2abCos C
⇒ 
= 
+ 
- 2(8 x 12) Cos
= 64 + 144 - 192 x 0.42262
= 208 - 81.143
= 126.857
x = 
= 11.2631
x ≅ 11
The length of the third side of the triangle is approximately 11 feet.
X-2=17
add two to both sides to cancel out the 2
x=19
First you will need to multiple 200 by .25 to see how much money Sam will make.
200 x .25 = $50
now you need to subtract that price by 10 because he spent $10 to get the stickers.
50 - 10 = $40
Sam is making $40 off the stickers.
let me know if you have any other questions

A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
