Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be right if a² + b² = c²
<span>a. 13 35 37
13</span>² + 35² = 1394 and 37² = 1369
1394 ≠ 369
<span>b. 6 9 10
</span>6² + 9² = 117 and 10² = 100
117 ≠ 100
<span>c. 5 12 13
</span>5² + 12² = 169 and 13² = 169
169 = 169 ← <span> right triangle
</span>d. 9 40 42
9² + 40² = 1681 and 42² = 1764
1681 ≠ 1784
The answer is <span>c. 5 12 13</span>

180-53-90
Just subtract the 2 angles you already have by 180
Answer:
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total charge in dollars
we know that
For x>700 min
so
For y=48.10
substitute
Multiply by 100 both sides
----> equation without decimals
solve for x
To find out the total minutes we need to sum
Basically what you're going to do is distribute -6 times -5 is 30 + 3z times -6 which is -18 seat so the answer is (30-18z)
