Answer:
To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°
so the SRT = Outer angle adjoined with angle SRT
angle SRT = 53° [°.° vertically opposite angles are equal]
Angle SRT + Angle STR + Angle RST = 180°
=>53° + 75° + Angle RST =180°
=> 128° + Angle RST = 180°
=> Angle RST =(180-128)°
= 52°
SO NO. <em><u>C</u></em> IS correct what Cate says is absolutely right
The equation of this straight line is y = 50x + 100.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
<h3>How to determine the equation?</h3>
In order to determine the equation from this graph of a linear equation, we would find the slope of the straight line by using this formula as follows:

Slope, m = 100/2
Slope, m = 50.
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
- x and y are the points.
- m is the slope.
- c is the intercept.
At point (4, 300), we have:
y = mx + c
300 = 50(4) + c
300 = 200 + c
c = 300 - 200
c = 100.
Therefore, the equation of this straight line is y = 50x + 100.

Step-by-step explanation:
Step-by-step explanation:
law of cosine :
c² = a² + b² - 2ab×cos(C)
with c being the side opposite of C.
so, in our case
3² = 3² + 3²×3 - 2×3×3×sqrt(3)×cos(A)
0 = 3²×3 - 18×sqrt(3)×cos(A)
27 = 18×sqrt(3)×cos(A)
cos(A) = 27/(18×sqrt(3)) = 3/(2×sqrt(3)) =
= 0.866025404...
A = 30°
FYI : since it is an isoceles triangle, C = A = 30°.
and therefore B = 180 - 30 - 30 = 120°.
as the sum of all angles in a triangle is always 180°.
