two congruent isosley triangles are joined as shown to form a pallalelagram the lagest angle of the palololagram is 116Write 2 equationssolve them to find the value of a and b

Step-by-step explanation:

Given two congruent, isosceles triangles are joined, as shown, to form a parallelogram, the largest angle of the parallelogram is 116 degrees. Write two equations. Write them find the value of a and the value of b.

We know that the sum of all the internal angles is 360 degree. So the equation will be

4 a + 2b = 360

According to the question the largest internal angle of the parallelogram is 116 degree.                So a + b = 116

Now we have the two equations as  

4a + 2b = 360

a + b = 116

Multiply the second equation by 4 we get

4a + 2b = 360

4a + 4b = 464

    Or – 2b = - 104

   Or b = 52

Now a + b = 116

Or a + 52 = 116

Or a = 116 – 52

Or a = 64

Therefore the values of  a and b are 64 and 52 degrees

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
