Answer:
ZB = 54
Step-by-step explanation:
Complementary angles add to 90 degrees
ZA + ZB = 90
x-15 + x+3 = 90
Combine like terms
2x-12 =90
Add 12 to each side
2x-12+12 = 90+12
2x = 102
Divide by 2
2x/2 = 102/2
x = 51
We want to find the measure of ZB
ZB = x+3
ZB = 51+3
ZB = 54
It is a parallelogram, so opposite angles are congruent.
4x = 100°
x = 25°
Sum of angles in a parallelogram is 360°.
360°-100°-100° = 160°
y = 160°/2 = 80°
<h3><u>Write 3 fractions, using 10 as the denominator, who's sum is 1</u></h3>
<em><u>Solution:</u></em>
Given that,
We have to write 3 fractions, using 10 as the denominator, who's sum is 1
We know that, fraction is written as:
We have to write 3 fractions with 10 as denominator
Add these to check if its sum is 1
When denominators are same, we can add the numerators
Thus the three fractions are:
Answer:
(3/2)x - 5 or 1.5x - 5
Step-by-step explanation:
y = mx + b
Whereas, m = slope, b = y intercept, and obviously x = the x variable.
We can find the slope by plotting the 2 points and using the rise-over-run method to give you 3/2 or 1.5.
We can find the y intercept by tracing a line through both points and to the y axis.
Hope this helps!
