Answer:
m∠ABC = 45°
Step-by-step explanation:
See the attached figure.
As shown in the figure
Line C B extends through point D to form the exterior angle that is 135 degrees.
So, m∠ABD = 135°
But m∠ABC + m∠ABD = 180°
∴m∠ABC = 180° - m∠ABD = 180° - 135°= 45°
Also, we should know that
m∠ABD = m∠BAC + m∠ACB
So, m∠ACB = 135° - 75° = 60°
========================================
<u>Very important note:</u>
If we replaced the location of B and C
SO, m∠ABC = 60° and m∠ACB = 45°
=========================================
<span>A study found that in a certain region housing prices had decreased by half over a ten year period. A dollar bill is used to depict the initial average cost of a home in this region. A second dollar bill to depict the average housing price at the end of the ten year period should be <em>ONE-FOURTH</em> the <em>AREA</em> of the original bill. </span><span />
Answer:
ok
Step-by-step explanation:
As the y intercept lies on the x-axis, x=0
To find the y-intercept, put x=0 into the equation:
Therefore,the y-intercept=9.
