What is angle a and c if b is 63 degrees? You will get 100 points for answering please help

Angle A measures 76°

Step-by-step explanation:

The three interior angles of a triangle will always equal 180. Therefore:

Solve for x. Add and combine like terms:

Subtract 78 from both sides:

Divide both sides by 3. So, the value of x is:

Angle A is given by:

Since we know that x = 38:

Angle A measures 76°

false

step-by-step explanation:

i looked it up

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
