<h2>QUESTION:- What is the value of y?</h2>

<h2>ANSWER:- </h2>

SUM OF ALL INTERIOR ANGLE = 180

y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y =  \frac{108}{2}  \\ y =  \frac{ \cancel{108}^{ \:  \:  \:  \tiny{54}}  }{ \cancel{2}}  \\ y = 54 \degree

the sum of triangle is 180 :

y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 75 \\ 2y = 108 \\ y =  \frac{108}{2}  \\ y = 54

solve the following system of equations. Enter the x-coordinate of the solution. Round answer to the nearest tenth. 5x+2y=22 -2x
melisa1 [442]

Answer:

A)  5x + 2y = 22

B) -2x + 6y = 3  We'll multiply A) by -3

A) -15x -6y = -66 Then we'll add B)

B) -2x + 6y = 3

-17x = -63

x = 3.7058823529

y = 1.7352941178

Jonathan was laying on the ground and enjoying the shade but now the sun is shining
avanturin [10]

Answer:

38.5°

Step-by-step explanation:

Given that the height of the building is 8 yard and the distance between Jonathan and the building is 10 yards.

The sun is at the top of the building, let the distance between Jonathan laying on the ground and the top of the building be x. Using Pythagoras:

x² = 10² + 8²

x² = 100 + 64

x² = 164

x = √164 = 12.86 yards

For a triangle with sides a, b, c and their respective opposite angles A, B, and C. The sine rule is given as:

\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}

Let the angle that the sunlight hit the ground be y°. The andle between the building and the ground is 90°. Therefore using sine rule:

\frac{8}{sin(y)}=\frac{12.86}{sin(90)}\\\\sin(y)=\frac{8*sin(90)}{12.86}\\\\sin(y)=0.622\\\\y=sin^{-1}0.622\\\\y = 38.5^0
