Break 48 into 40 and 8. 3(40) + 3(8). 3 times 40 is 120 and 3 times 8 is 24. So, 120+ 24= 144
Answer:
4y=48
y=48/4
y=12
therefore,the value of y is 12
Answer:
42+x=90
Step-by-step explanation:
Complementary angles are when their measures add up to 90°
Therefore, if angle a is 42° you would find angle b by subtracting 42° from 90° which is shown in equation number three.
Answer:
X - axis
Step-by-step explanation:
Since in the above reflection x coordinate remains the same and y-coordinate changes from 1 to - 1, hence point H is reflecting across X - axis.
