Question

Help me with this math exercice please

if A=28° and C =×° si what is B=?





​

Answer 1

? = ( 152 - x )°

Explanation:

• We know that sum of all angles of triangle is 180°.

28° + x° + ? = 180°

subtract 28° from each side

28° - 28° + x + ? = 180° - 28°

x + ? = 152

Now, subtract x from each side

x - x + ? = 152 - x

? = 152 - x

Answer 2

? = 152-x

Explanation:

The sum of the angles of a triangle equal 180

A+B+C = 180

28 + ? +x = 180

? = 180 - 28 - x

? = 152-x
