X comes first, then y....so ur points are (-5,3)
Answer:
see explanation
Step-by-step explanation:
Since the base angle are congruent, both 44° then the triangle is isosceles.
Then the 2 legs are congruent, that is
4x - 7 = 2x + 1 ( subtract 2x from both sides )
2x - 7 = 1 ( add 7 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus legs are both 4x - 7 = 4(4) - 7 = 16 - 7 = 9 and base = x + 3 = 4 + 3 = 7
As a check 9 + 9 + 7 = 25 → correct
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180 for y, that is
y = 180 - (44 + 44) = 180 - 88 = 92
Finally
x = 4
y = 92
angles are 92°, 44° and 44°
sides are 9, 9 and 7
Answer:
x = -2
Step-by-step explanation:
The root will touch the axis and bounce off when the exponent is even. In that case, that means (x + 2)² is the binomial that will bounce. Therefore, the root which bounces and touches the x-axis is x = -2.
Answer:
m<D = 20.7
Step-by-step explanation:
Let's remember that all three angles in the interior must be equal to 180 degrees
Second, you're given the measure of tw angles with the thrid missing
Let's solve:
(5x-8)+ (4x-19)+ x = 180 .... x is the third angle which is not given
Now simplify:
5x- 8+ 4x- 19 +x = 180
Combine like terms:
10x -27 = 180
10x = 180+ 27
Now plug in the value of x into each of the angle measures:
5*20.7 - 8= 95. 5
4*20.7 - 19= 63.8
Now let's see how much is the other angle based on our data:
95.5+ 63.8+ x= 180
x= 180- 95.5 -63.8
m<D = 20.7
10x = 207
x= 207/10
x= 20.7
