Let us draw a triangle ABC with A=15° ,B=113° and b=7.
Please see the attached image.
We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have
Apply Sine rule in the triangle ABC, we get
Therefore, we have
Answer:
Six cases are enough to construct more than one isosceles triangle
Step-by-step explanation:
An Isosceles triangle is a triangle in which at least two of it's sides are congruent.
If two of the three sides of a triangle are congruent, but the third side is of a different length, the triangle is isosceles.
If all three sides of the triangle are congruent, even though this is an equilateral triangle, it satisfies the condition of an isosceles, and it is ok to still it isosceles.
Julius might decide to split information for a better explanation, it doesn't matter the number of cases he has, but six cases should be enough to draw an isosceles triangle.
Answer:
The answer is B) $110.50 for 6.5 hours of work
Step-by-step explanation: Divide 119.00/7. This equals 17. To find anything equivalent to this, divide the amount of money earned by the hours worked. Starting from A, you divide 120.50 by 8.5. This equals 14.1764706... This clearly isn't equivalent. Then you move downward to option B. Here, you divide 110.50 by 6.5. This then gives you 17. As you can see, it is equivalent to the rate that the printer earns; therefore, this is the only option.
So, we know this:
<span> 5x+10y = 800
and we also know that the number of larger vehicles was 50.
So we can substitute:
</span>
<span>5x+10y = 800
</span>
<span>5x+10*50 = 800
and calculate:
</span><span>5x+500 = 800
and now subtract 500 from both sides:
5x=300
and divide by 5:
x=60.
and this is our answer: there were 60 smaller vehicles washed!
