Answer :-
- ∠C = 57°
- ∠BAC = 75°
Step-by-step explanation :-
To Find,
- ∠C
- ∠BAC
Solution,
Given that,
- ∠ABC = 68°
- ∠CAE = 105°
Therefore,
The measure of ∠BAC is,
➮ ∠BAC + ∠CAE = 180° ....... linear pair
➮ ∠BAC + 105° = 180°
➮ ∠BAC = 180° - 105°
➮ ∠BAC = 75° ★
Hence, the measure of ∠BAC is 75°.
Now, Verification
➮ 105 + 75 = 180
➮ 180 = 180
L.H.S = R.H.S
Hence, Verified !
The measure of ∠C is,
Let us assume ∠C as x,
➮ ∠BAC + ∠ABC + ∠C = 180° .... angle sum property of triangle
➮ 75° + 68° + x = 180°
➮ 123° + x = 180°
➮ x = 180° - 123°
➮ x = 57 ★
Hence, the measure of ∠C is 57°.
Now, Verification
➮ 75 + 68 + 57 = 180
➮ 123 + 57 = 180
➮ 180 = 180
L.H.S = R.H.S
Hence, Verified !
