I read this story last year for my 7th grade year. The correct answer is A!
Answer:
Step-by-step explanation:
i² = -1
-8(-1) + 3 = 8 + 3 = 11
70.4
The word "of" means to multiply, so 22% or .22 * 320 = 70.4
Step-by-step explanation:
I think what is meant in the triangle ABC we have the three angles.
the sum of all angles in a triangle is airways 180 degrees.
so,
180 = A + B + C
180 = 42 + B + C
now, we know also that
B = 5×C
so, we can use that above
180 = 42 + 5×C + C
138 = 6×C
C = 138/6 = 23 degrees
B = 5×C = 5×23 = 115 degrees
