Step-by-step explanation:
General Form of an equation of a line is given by: ![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where,
m is the slope, and
b is the y-intercept (point where line cuts the y-axis)
Also, parallel lines have equal slopes.
Equation of first plane is given as ![d=3.67t+4.81](https://tex.z-dn.net/?f=d%3D3.67t%2B4.81)
Comparing this with general form of a line, we see that 3.67 is the slope and 4.81 is the y-intercept.
<em>The </em><em>second plane </em><em>is going </em><em>parallel</em><em> to this. So slope should be same. Hence </em><em>second plane has slope of 3.67. </em><em>We can write:</em>
<em>
</em>
<u>To find the equation of second plane</u>, we need to solve for c. Also, a point given for second plane is
, substituting these values into the equation we got, we get the value of c:
![2.14=3.67(0)+c\\2.14=0+c\\c=2.14](https://tex.z-dn.net/?f=2.14%3D3.67%280%29%2Bc%5C%5C2.14%3D0%2Bc%5C%5Cc%3D2.14)
We already know m and now we know c, so we can write final equation as:
![d=3.67t+2.14](https://tex.z-dn.net/?f=d%3D3.67t%2B2.14)
Answer choice C is right.
First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65
