Sum of angles in a triangle is 180°:
180 - 50 - 62 = 68
Sum of angles in a triangle is 180°:
180 - 80 - 53 = 47
Sum of angles in a triangle is 180° / Vertically opposite:
180 - 68 - 47 = 65°
Answer: 65°
Answer:
four pack of notebooks for $4.56
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
Answer:
C
Step-by-step explanation:
When you are given any number to an exponent, you need to multiply it by itself as many times as the exponent's number. For example, if you got 4^7, you would multiply 4 * 4 * 4 * 4 * 4 * 4 *4 for a total of 7 times. In this case, it is 1/2 * 1/2 * 1/2 because the exponent is 3, meaning you do that 3 times.
The amount paid to the man in the first year given the total he received in four years is $3,700.
<h3>Equation</h3>
- Amount paid in the first year = x
- Amount paid in the second year = (x + 500)
- Amount paid in the third year = x + 500 + 500
= (x + 1000)
- Amount paid in the fourth year = x + 500 + 500 + 500
= (x + 1500)
Total payment = first year + second year + third year + fourth year
x + (x + 500) + (x + 1000) + (x + 1500) = 17,800
x + x + 500 + x + 1000 + x + 1500 = 17800
4x + 3000 = 17,800
4x = 17,800 - 3000
4x = 14,800
x = 14,800/4
x = $3,700
Therefore, $3,700 was paid to the man in the first year.
