Hello,
sin (30°)= cos (60°)=1/2 (complementary angles)
sin D= cos E
Answer C
Answer:
x - 3 = y
Step-by-step explanation:
The answer is the third equation.
This is because the y-intercept is -3 and the x-intercept is at (2,0) (you can find the x-intercept by making "y" = 0). The only equation that has both of these is the third one.
If c is a perfect square, then there is an even number of rectangular models that represent the polynomial. Then the correct option is B.
<h3>What is a polynomial?</h3>
Consider the polynomial x² + bx + c, where b and c are positive integers. If the polynomial is factorable, it can be modeled with a rectangle with a distinct length and width.
The table shows the relationship between some values of c and the number of rectangular models.
Then the relationship between c and the number of rectangular models representing a factorable polynomial x² + bx + c will be
If c is a perfect square, then there is an even number of rectangular models that represent the polynomial.
Then the correct option is B.

Answer:
side a = 17.58722
angle a = 41.96 degrees
angle b = 47.04 degrees
Step-by-step explanation:
Obtuse Scalene Triangle
Side a = 19.25
Side b = 17.58722
Side c = 26.3
Angle ∠A = 47.04° = 47°2'23" = 0.821 rad
Angle ∠B = 41.96° = 41°57'37" = 0.73234 rad
Angle ∠C = 91° = 1.58825 rad
C=91°B=41.96°A=47.04°b=17.587a=19.25c=26.3
Area = 169.25122
Perimeter p = 63.13722
Semiperimeter s = 31.56861
Height ha = 17.58454
Height hb = 19.24707
Height hc = 12.87082
Median ma = 20.19553
