Answer:
Yes!
Step-by-step explanation:
We know that right triangles follow the Pythagorean Theorem, where
So we will put our side lengths into this formula, keeping in mind that c = the hypotenuse, which is the longest side. a and b are fairly arbitrary.
If this works, we know it's a right triangle.
1089 + 1936 = 3025
3025 = 3025
It worked! It's a right triangle!!
1!+2!+3!....+99! That’s the hardest I’ve seen
Answer:
Yes: A, B, F
No: C, D, E
Step-by-step explanation:
2(x + 7) = 36
First divide both sides by 2
(x + 7) = 36/2
x + 7 = 18
Or
2(x + 7) = 36
2x + 14 = 36
Or,
2(x) + 2(7) = 36
Multiplying both sides of <span>−1/3x≤−6 by -3 results in "x is equal to or greater than 18."
Note that multiplying such an inequality requires reversing the direction of the inequality symbol.
I subst. 18 for x in </span><span>−1/3x≤−6 as a check, and found that the resulting inequality is true.</span>
Hello!
When trying to find the sine of an angle, we can use the following formula:
sin B =
In this case, we need to find the side opposite ∠B (which would be AC) and the hypotenuse (which would be BC). Now take the individual values of these two sides and insert them into the formula above:
sin B =
Reduce the fraction above to reach a value of 0.92. We have now proven that
the approximate value of sin B is 0.92
The answer to this problem is
B.
I hope this helps!
