Answer:
m∠2 = 57°
Step-by-step explanation:
From the triangle given in the picture,
By applying triangle sum theorem in ΔABC,
m∠BAC + m∠ABC + m∠BCA = 180°
90° + m∠2 + 33° = 180°
m∠2 + 123° = 180°
m∠2 = 180° - 123°
m∠2 = 57°
Answer:
Step-by-step explanation:
100-15=85
85-34= 51
I first subtract 15 from 100 because 15% is out of 100% And I got 85 then I subtract 34 from 85 and then I got 51
hope this helps
C. It is always a rational number. You cannot determine its sign without knowing the values of a and b.
Part a b2+49−(b−7)2
Distribute:
=b2+49+−b2+14b+−49
Combine Like Terms:
=b2+49+−b2+14b+−49
=(b2+−b2)+(14b)+(49+−49)
=14b
Answer:
=14b
part b
(2a+6b)2−24ab
Distribute:
=4a2+24ab+36b2+−24ab
Combine Like Terms:
=4a2+24ab+36b2+−24ab
=(4a2)+(24ab+−24ab)+(36b2)
=4a2+36b2
Answer:
=4a2+36b2
