you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c
16.4cm is your answer!
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
The answer will be 76 or B. Hope it help!
Answer:
x=45
Step-by-step explanation:
a=135
x+135=180
x=180-135
x=45
All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.
8 - 15 = -7
It would be -7<span>°C at midnight. I hoped this helped! :)</span>
