Answer:
126
Step-by-step explanation:
We multiply 42 × 3= 126
The measure of the angle is 126.
The simplified expression should be
ab(5+9-1)
once factorized
Answer:
x=7 because 25-4=21 and 21 ÷3=7
Angles in a triangle adds up to 180
180 - (25.5 +120.2) = 34.3
So, missing angle is 34.3 degrees
Hope this helps!
