Answer:
Blue
Step-by-step explanation:
I used a graphing calculator called Desmos.
4x+5x = 90
9x = 90
x = 10
10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12
answer
<span>d) x = 10, y = 12</span>
Answer:
The correct option is D ....
Step-by-step explanation:
Angle is ending at the point = (-3, -4)
Signs of both x and y are negative therefore it is in the third quadrant.
To find the the tangent of an angle we have to find the ratio of the length of the opposite side to the length of the adjacent side.
In this question the opposite side of the angle is of 4 units and the adjacent side of the angle is 3 units.
tanθ = y/x
tanθ = -4/-3
tanθ = 4/3
Thus the correct option is D ....
Answer:
3/4
Step-by-step explanation:
Answer:
28 degrees
Step-by-step explanation:
step 1
Find the measure of angle 1
----> by supplementary angles
step 2
Find the value of x
----> by corresponding angles
substitute
step 3
Find the measure of angle 2
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
substitute
