1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
Answer:
y = -4x + 2
Step-by-step explanation:
To figure out the slope, plug the coordinates in the formula.
y2 - y1 / x2 - x1
= 6 - (-6) / -1 -2
= -4
Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b
y = -4x + b
-6 = -4(2) +b
-6 = -8 + b
2 = b
We know that
in the triangle ABC
∡A+∡B+∡C=180°
∡C=180-(50+100)-------> ∡C=30°
triangle ABC and triangle XYZ are similar
so
∡X=∡A
∡Y=∡B
∡Z=∡C
hence
∡Z=30°
the answer is∡Z=30°
The answer is 9 because 6/2 is 3 and if you multiply that by 1 it's 3 and if you multiply 3 by 2 you get 6 so you add them up and get 9.
