Question

4. If triangleABC - triangleXYZ, angleC-60, angleB - 75 then find angle X?
​

Answer 1

Answer:

45 degrees..........

Answer 2

first angle = - 60

second angle = - 75

let the third angle = x

we can find x with the help of triangle sum property

La + Lb + Lc = 180

- 60 + (-75) + x = 180

- 60 - 75 + x = 180

- 135 + x = 180

x = 180 + 135

x = 315

so the third angle = 315

hope this help !!!
