The answer is y = -2x-2
To find the slope of a line perpendicular to your equation, you just need to find the reciprocal. This just means flip the signs (change positive to negative, or negative to positive) and flip the numerator and denominator. So if you have 1/4 as your slope, the perpendicular slope would be -4/1 (which is just negative 4).
I changed the “b” from -3 to -2 so it would run through the points (-2, 2).
I hope this helps :)
Answer:
∠ C ≈ 66.8°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanC = 
= 
= 
, then
∠ C = 
( ) ≈ 66.8° ( to the nearest tenth )
Answer:
m∠1=80°
m∠2=112°
m∠3=131°
m∠4=80°
m∠5=37°
Step-by-step explanation:
First you have to find m∠2
To do that find m∠6 (I created this angle shown in pic below)
Find m∠6 by using the sum of all ∠'s in a Δ theorem
m∠6=180°-(63°+49°)
m∠6=68°
Now you can find m∠2 with the supplementary ∠'s theorem
m∠2=180°-68°
m∠2=112°
Then you find m∠5 using the sum of all ∠'s in a Δ theorem
m∠5=180°-(112°+31°)
m∠5=37°
Now you can find m∠1
m∠1=180°-(63°+37°)
m∠1=180°-100°=80°
m∠4 can easily be found too now:
m∠4=180°-(63°+37°)
m∠4=80°
m∠3=180°-49°
m∠3=131°
Answer:
x ≈ 11.1
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos42° = 
= 
( multiply both sides by 15 )
15 × cos42° = x, then
x ≈ 11.1 ( to the nearest tenth )
