Answer:
16
Step-by-step explanation:
Triangles XWY and ZWY are congruent because of AAS . the two 90 degree angles are congruent,∠xwy and ∠zwy are congruent because ∠xwz is being bisected, and wy is congruent with wy beacuse of the reflexive property. Since the two triangles are congruent zy must ve congruent to xy because of CPCTC. Since the two linew are congruent and xy=16, zy must also equal 16.
Answer:

And replacing the value of
we got:

Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:

And the surface area for a cylinder is given by this formula:

And replacing the info given we got:

And replacing the value of
we got:

Y+38°= 180 beacuse if a and b are parallel they are
co interior angles. This means that they will at to 180.
y=180-38= 142°
Answer: 142°

Answer:
x = 17 and y = 37
Step-by-step explanation:
Let the numbers be x and y.
y = 3 + 2x
xy = 629
substituting y in the second equation we get
x(3+2x) = 629
3x + 2
= 629
2
+ 3x - 629 = 0
Solving a quadratic equation by using its formula:
x = [-3 ±√(9-4(2)(-629)] / 4
x = [-3 ± √5041] / 4
x = [-3 ± 71] / 4
x = 17 and 
Ignore the negative number in x and just use x = 17 in the first equation we get
y = 3 + 2(17) = 37
