The sum of the three interior angles of a triangle is 180 degrees.
A- 3 a = 180°
B- a + 55° + 36° = 180°
C- x + y + z = 180°
D- x3 = 180°
E- x · y · z = 180°

A) 3a = 180°

B) a+ 55° + 36° = 180°

C) x + y + z = 180°

Step-by-step explanation:

The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )

The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.

The terms don't have to be similar, for instance the B option,

a+ 55° + 36° = 180°

since you could find the value of a.

The same thing goes for C.

(Extra)

It is not D since x is multiplied with 3, not giving the sum.

It is not E since all the 3 terms are multiplied, not giving the sum.

C

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
