50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
Answer:
G=L^3/(T^2M)
Step-by-step explanation:
- G=(Fr^2)/Mm
- G=(ML^3)/(T^2M^2)
- G=L^3/(T^2M)
we know that
The sum of the internal angles in the triangle must be
degrees
see the attached figure with letters to better understand the problem
Step 
<u>Find the measure of the angle x</u>
In the triangle ABC

solve for x



therefore
<u>the answer Part a) is</u>
the measure of angle x is 
Step 
<u>Find the measure of the angle z</u>
we know that
--------> by supplementary angles
substitute the value of x



therefore
<u>the answer Part b) is</u>
the measure of angle z is 
Step 
<u>Find the measure of the angle y</u>
In the triangle ACD

solve for y




therefore
<u>the answer Part c) is</u>
the measure of angle y is 
Answer:
d.) none are correct
Step-by-step explanation:
it should be reflection over the y-axis then reflection over the x-axis
