Answer:
50degrees
Step-by-step explanation:
The sum of angle in the triangle XYZ is 180degrees, hence;
<X + <Y + <Z = 180
Given
m<X = 80degree
m<Y = m<Z
Required
m<Z
Substitute the given angle
80 + m<Z + m<Z = 180
80 + 2m<Z = 180
2m<Z = 180 - 80
2m<Z = 100
m<Z = 100/2
m<Z = 50degrees
Hence the measure of angle Z is 50degrees
Answer: p = -2w + 20
<u>Step-by-step explanation:</u>
If the student had 20 pencils but now has 18 pencils, he uses pencils at a rate of 2 per week. So, m = -2 (negative because he is decreasing the amount of pencils). The student started with 20 pencils so b = 20
Use the y = mx + b but replace "y" with "p" and replace "x" with "w" and input the m and b as stated above:
p = -2w + 20
