if there are 4 numbers that average to 60, when mutiplied they must come up to: 60*4= 240
100+30+45= 175
240-175= 65
PROOF:
100+30+45+65= 240
240÷ 4
= 60
Answer:
Rational Number
Step-by-step explanation:
A rational number : A number that can be in the form of
q
/p , where p and q are integers and q is not equal to zero.
We have two sides and one angle opposite to one of the known sides.
Begin with applying the Law of Sines to find angle A:
= <span>
Then, solve for sin A:
</span>sin A =
Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17
We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
Answer:
I would say B.
Step-by-step explanation:
Perpendicular lines meet at a right angle.
Answer:
9.
10. B = 16 ft, H = 15 ft

Step-by-step explanation:
<u>Area Of The Triangle
</u>
(9)
The area of a triangle of base length B and height H is
provided the base and height are perpendicular to each other
(10)
The dimensions of the given triangle are not the ones needed to compute its area. We need to calculate the height of the triangle, and we have the hypotenuse of one of the identical right triangles. To find the height, we must apply Pythagoras's theorem:
Note the length of one leg of the triangle is half the length of the base. We need to solve for H:
Thus
(11)
Now we compute the area of the triangle
