Question

The second angle of a triangle is the same size as the first angle .The third angle us 12 degree largar than the first angle . Find all three angles

Answer 1

Answer:

Hey mate, this is your answer.

Step-by-step explanation:

STEP 1: Define x:

Let one of two angles of the same size be x

Therefore, the other different one will be x - 12

.................................................................................................

STEP 2: Find x:

Sum of angles in a triangle is 180°

x + x + (x - 12) = 180

x + x + x - 12 = 180

3x - 12 = 180

3x = 192

x = 64

.................................................................................................

STEP 3: Find the 3rd angle

x - 2 = 64 - 12 = 52

................................................................................................

The angles are 64, 64 and 52
