So really all you have to do is simply the expressions on top to match them.
Starting with (4t-8/5)-(3-4/3t), distribute the negative sign to the right portion in parentheses, then distribute it all out and you will get 16/3t- 23/5
Basically, use distribution to simplify, here's all the matches:
(4t-8/5)-(3-4/3t) --> 16/3t- 23/5
5(2t+1)+(-7t+28) --> 3t+33
(-9/2t+3)+(7/4t+33) --> -11/4t+36
3(3t-4)-(2t+10) --> 7t-22
Correct Answer: A. 2(n+8).
Answer:
The Exterior Angle of a Triangle Formula states that the measure of an exterior angle is equal to the sum of its remote interior angles. Therefore, r + 58 = 130 which means r = 72°.
X is:
tan50 = 28 / x
1.19 = 28 / x
1.19 / 28 = x
x = 0.04
But Im not sure
About the area of triangle
You can use the both formula
