Answer:
<h2><u><em>
52° & 78°</em></u></h2>
Step-by-step explanation
Two angles of a triangle are in the ratio of 2:3 if the third angle is 50 degree find the other two angles
the sum of the interior angles in a triangle is 180°
so
180 - 50 = 130°
130 : 5 = 26° (unit)
26 * 2 = 52°
26 * 3 = 78°

------------
- 2 : 3 = 52 : 78
- 0.66666666666 = 0.66666666666
The answer is good
Answer:
y=2
-7x-4
three linear equations
c=-4 ;4a+b=1 ; 9=a-b
Step-by-step explanation:
Simply assume a standard parabola equation y=a +bx +c
(here a, b, c are three independent variables)
Three coordinates as shown in graph are (0,4), (4,0) ,(-1,5)
Now put these points in the equation of parabola and get three linear equations.
[1] c=-4
[2] 4a+b=1
[3] 9=a-b
Now substitute value of a from equation 2 into 3 in terms of b
a= 
9=-b
b=-7
a=2
y=2 -7x-4
I'm not too sure, as i'm learning this at the moment too. correct me if i'm wrong but wouldn't both be (infinity, infinity) ?? since there's arrows meaning its infinite
