It looks like you have to find N and then multiply each angle measure given to finds the correct angle measures. Remember, if you add up all of the interior angles in a triangle, it adds up to 180 degrees. So 3.2n + 6.4n + 2.4n = 180 degrees. You must solve for N. Combine all of them. The sum is 12n = 180 degrees. I'll let you solve for N. When you do, multiply each number in the triangle by N to find each angle measure. The formulas above are for the area of different geometric shapes, but won't help with this question.
Answer:
plot the reflection by finding the corresponding points by pretending that y=x-6 is the x-axis, so like (4,-1), (0,-5), (0,-3)
Step-by-step explanation:
Answer: Its B
Step-by-step explanation:
I did this test and got it right
F(3)= 2(3)^2-5(3)+9
=2(9)-15+9
=18-15+9
=3+9
=12
f(3)=12 or B
