M+1.51 is your answer. first you calculate the difference and then you reorder the values.
so you have a 148+85+85=318, 360-318=42 is the measure of angle T because all four angles together make 360
Answer:
x = ± 
Step-by-step explanation:
Given
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides, thus
x = ± 
Plus or minus 3. (The 1st answer)
x^2 means (-3*-3) which equals 9
x^2 means (3838) which also equals 9
6*9=54
