Y is a 97 degree angle
Angle z is 83 because the sum of all interior angles in a triangle is 180
180-55-42 = z
83 = z
Angles y and z are supplementary angles, so they add up to 180.
Since z = 83 and 180 - 83 = 97, angle y is 97 degrees
Option D:
Measure of arc BEC = 228°
Solution:
Given angle A = 114° and vertical angle of A = 0.
<em>If two chords intersect inside the circle, then the measure of each angle is one half of the sum of the measures of the arcs intercepted by the angle and its vertical angle.</em>
Multiply by 2 on both sides, we get
Measure of arc BEC = 228°
Option D is the correct answer.
14.4%
L*W*H=V=10*9*4.5=405 in^3.
that is 50.5 in^3 over the estimate, or 14.4%
Answer:
14
Step-by-step explanation:
We have found one solution to the equations that the two equations intersect at the point (2.5,-1.5).
<h3>What are equations?</h3>
The equation is actually a relationship between the numbers and the variables. In this question we have two equations y=2x²-6x+1 and y=-x+1 so by equating them we can find the value of x which is the intersecting point of the two lines.
Now the solution of the equations:-
y=2x²-6x+1
y=-x+1
2x²-6x+1 = -x+1
2x²=5x
x=5/2=2.5
y=-2.5+1=-1.5
Hence the one solution to the equations that the two equations intersect at the point (2.5,-1.5).
