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.
Answer:
the answer is 1/4 because if you add up all of the numbers you get 100 which is easy to get a fraction out of and because the orange juice proportion is 25 you get 1/4
