Answer: C) 8 cm
Step-by-step explanation:
Given: In △ABC AB=8 cm , m∠A=70° , and m∠B=55° .
The angle sum property of triangle says that the sum of all interior angles in a triangle is equals to 180°.
⇒ m∠A+m∠B+m∠C=180°
⇒70°+55°+m∠C=180°
⇒m∠C=180°-125°
⇒m∠C=55°
Now, in △ABC m∠C= m∠B= 55°
⇒AB=AC [∵ Sides opposite to equal angles of a triangle are equal]
⇒ AC= 8 cm.

it is D
Step-by-step explanation:
Answer:
387
Step-by-step explanation:
To evaluate 3 - 6( Z - 2) ^3 at Z = -2, replace Z with -2:
3 - 6( -2 - 2) ^3
Simplify this result, obtaining 3 - 6( -4) ^3.
According to order of operations rules, exponentiation must be done first here, before multiplication and before subtraction. Therefore:
3 - 6( -4) ^3 → 3 - 6( -64). Again, these rules require that we multiply before subtracting:
3 - 6( -64) = 3 + 384, or 387
