Answer:
Angela, a proportion is two equal ratios, kinda like 3/4 = 6/8.
If we call the number of cars c, then our proportion is 3/10 = c/100.
Cross multiplying, we get 10c = 300.
Dividing both sides by 10, c = 30.
Answer:
The 3 possible values of x are;
6, 4 and 2
Step-by-step explanation:
If the triangle is isosceles, then two of the sides must be equal
So we equate the sides, 2 at a time to get the different values of x
3x + 4 = 2x + 10
3x-2x = 10-4
x = 6
3x + 4 = x + 12
3x-x = 12-4
2x = 8
x = 8/2 = 4
2x + 10 = x + 12
2x - x = 12-10
x = 2
Answer: A right triangle.
Step-by-step explanation:
This is because an acute triangle would have all of its three sides acute while an obtuse one would have two acute angles as well, but also an obtuse one. If the question is specifically asking for a triangle with exactly two acute angles, a right triangle would be the answer.
Answer:
<em>2.399</em>
Step-by-step explanation:
Given the trigonometry expression:
tan(sin^-1((-12/13))
We are to find the exact value
tan(sin^-1((-12/13)) = tan(sin^-1((-0.9231))
tan(sin^-1((-12/13)) = tan(-67.38)
Also note that tan(-theta) = -tan theta
tan(-theta) = -tan67.38
tan(-67.38) = -2.399
<em>The exact value is 2.399</em>
