Every triangle angles add up to 180.
So because one angle is 90 degrees you would subtract it from 180 to get 90 and then divide it by two which is 45 degrees.
Hope this helps, have a nice day! :)
Answer:
![\dfrac{7}{12}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B12%7D)
Step-by-step explanation:
1. Find the Greatest Common Factor of the numerator and denominator.
The prime factors of 35 are <u>5</u>, 7, 35
The prime factors of 60 are 2, 3, 4, <u>5</u>, 6, 10, 12, 15, 20, 30, 60
The only common factor of 35 and 60 is 5.
2. Divide the numerator and denominator by the Greatest Common Factor.
![\dfrac{35}{60} = \mathbf{\dfrac{7}{12}}](https://tex.z-dn.net/?f=%5Cdfrac%7B35%7D%7B60%7D%20%3D%20%5Cmathbf%7B%5Cdfrac%7B7%7D%7B12%7D%7D)
Ok so the lines with two triangles are parralel to eachother. The lines with one are parallel to eachother.
The angle of 109° and angle of z° equal eachother. Z=109°
Since 109°, 33° and y° form a triangle, the sum of the angles will equal 180. Add 109 and 33 to get 142. Subtract 142 from 180 to get y°=38°.
Since z=109, this means that the triangle is congruent with the other. Since the congruent triangles are in a rhombus, then the angles are flipped. Thus, angle x =33°.
z=109°
y=38°
x=33°
Answer:
x = –4
Step-by-step explanation:
x = –koef x / (2•koef x²)
It would bw 12 99/100 and then 1299/100
