Answer:
5
Step-by-step explanation:
A 30-60-90 triangle's sides equal as follows:
Hypotanuse= x (a number)
Long side= x/2( also can be calculated as x* 1/2) * 
Short side = x/2 or x * 1/2
Answer:
x=19
Step-by-step explanation:
(7x+7) + (2x+2) = 180
9x + 9 = 180
9x=171
x=19
Answer:
A=675cm²
Step-by-step explanation:
Area of triangle=1/2(base × height)
A=1/2(b × h)
A=1/2(6x × 9x)
where x=5
A=1/2(6×5×9×5)
A=1/2(30×45)
A=1/2(1350)
divide 1350 by 2
A=675cm²
Jason earns 680$ in 40 hours.
Step-by-step explanation:
- Property used to solve this problem is <em>Algebra.</em>
- Jason earns <em>17$</em> which is fixed earning irrelevant of hours.
- hours is variable which means <em>n</em>.
- how much will he earn = 17 * number of hours (n).
- For n = 1, amount of money he would earn = 17 *1 = 17$
- For n =2, amount of money he would earn = 17 *2 = 34$
- For n = 3, amount of money he would earn = 17*3 = 51$
- For n = 40, amount of money he would earn =17*40 = 680$
- Algebra is branch of mathematics which help in puzzles and many problems from day to day life.In Algebra letters stands numbers and there operations can be done in the numbers.
