Answer:
C-7
Step-by-step explanation:
7-2=5
meaning 5 would not be either equal or less than 3.
Y = 1/3x + 2
Explanation- find the slope. By looking at the first point, you go up 1 and over 3, making slope 1/3. Or you can find the slope with the equation:
m = y2-y1
———
x2-x1
The y intercept is on the y axis at 2.
So, The equation is y = 1/3x + 2
Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° =
Or, AB =
So, AB = 26.54 cm
Again, Sin 37° =
So, BC =
Or, BC =
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
Answer:
yes
Step-by-step explanation:
For the given sides to form a triangle.
The sum of any 2 sides must be greater than the third side.
12.2 + 6.8 = 19 > 6.5
12.2 + 6.5 = 18.7 > 6.8
6.8 + 6.5 = 13.3 > 12.2
Thus the 3 given sides form a triangle
Answer:
A(3,-1) and B( -2,1)
Step-by-step explanation:
2x+5y=1. , or. y=(1–2x)/5………….(1)
x^2+5xy-4y^2+10=0…………………..(2)
Putting y=(1–2x)/5 from eqn. (1)
x^2+5x.(1–2x)/5–4/25.(1–2x)^2 +10=0
or. 25x^2+25x.(1–2x)-4.(1+4x^2–4x)+250 = 0
or. 25x^2+25x-50x^2–4–16x^2+16x+250=0
or. 41x^2–41x-246=0
or x^2– x - 6=0
or. (x-3).(x+2)=0
=> x= 3 or -2
But y=(1–2x)/5
=> y= (1–6)/5 or. (1+4)/5
hence, y= -1. or. 1
