An Isosceles triangle has single measures 55,55,and 70. The side across from the 70 angle is 10 inches long. How long are the ot
UkoKoshka [18]

Answer:

8.717 both the sides

Step-by-step explanation:

Given:

Let ABC be the given triangle with

angle A= 55

angle B=55

angle C= 70

side across angle C, c= 10 inches

side across angle B, b =?

aide across angle A,a=?

Now using the law of sin to find a and b:

                a/sinA=c/sinC

                a= (c/sinC)(sinA)

Putting the values:

                a= (10/sin70)(sin55)

                a= 8.717

As the given triangle is isosceles so side a=b

hence a=b= 8.717 inches !

Write a numerical pattern that represents the rule y=x+3 starting with x=0
disa [49]
Just replace x with 0
y=0+3
y=3
and then 1
y=1+3
y=4
and then 2
y=2+3
y=5
and so on
the numerical pattern looks like this:
3 , 4 , 5 , 6 , 7 , 8 , 9.....

How to find the missing side of a triangle while only given angles and one side?
OLga [1]
Hi there!

Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)

Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!
