If in a Delta ABC, /A=45^@,/B=75^@, then...

If in a `Delta ABC, /_A=45^@,/_B=75^@,` then `angle C = ?`

A

`60^(@)`

B

`50^(@)`

C

`70^(@)`

D

`80^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
In `Deltaxyz `
`anglex+ angley+anglez=180^(@)" "` (Angle sum property)
or `45^(@)+75^(@)+z=180^(@)`
or ` z=60^(@)`
