The sum of all the angles of the triangle is 180°.
80 + 3x + x = 180°
80 + 4x = 180°
4x = 180 - 80
4x = 100
x = 100/ 4
x= 25
I think the answer is B, b/c if u multiply the 234 times 3 you will get 702.
Hope This Helped.
Answer: -8
Step-by-step explanation:
Solve for x
5 (x − 2) = 3 (x − 4) − 14
5x − 10 = 3 (x − 4) − 14
5x − 10 = 3x − 12 − 14
5x − 10 − 3x = −26
2x = −26 + 10
2x = −16
x = −8
Answer:
Step-by-step explanation:
Given
The attached figure
Solving (a): EF
Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.
So, EF will be calculated using Pythagoras theorem which states:
Take the positive square roots of both sides
Solving (b): GH
Since m is a perpendicular bisector, then GH = FG
Solving (c): EH
Since m is a perpendicular bisector, then EH = EF
Both the equation show a graph of a parabola. The equation y=-x^2+1 is a parabola opening downward since the x variable has a negative sign. While the equation y=x^2 is also a parabola opening upward since x^2 is positive. Both parabola have axis of symmetry on the y-axis. Vertex for the first parabola is on (0,1) while the second parabola is at the origin.
