I wrote the problem, so that you could see actual square roots and not sqrt every time. I also showed the distance formula, which is essential to solving this problem.

X is the midpoint of WY and V is the midpoint of WZ.
arlik [135]

Answer:

50

Step-by-step explanation:

By the triangle midsegment theorem, 2(VX)=YZ.

This means that 2(t-25)=t, and thus t=50.

4) Jessica sold half of her comic books and
Tomtit [17]

Answer:

a) Let her  comic books be x

b) as she sold half it will be

  \frac{x}{2} + 8 = 13  ( as she sold half and then she bought 8 more that means plus and then now she have 13 that means = 13)

c ) to solve to find the books she have we need to

\frac{x}{2} + 8 = 13

Transpose

\frac{x}{2}  = 13 - 8

\frac{x}{2} = 5

x = 5 × 2

x = 10

the comic books were 10

we can even cross- check to see if the value is right instead of x put 10

\frac{10}{2} + 8 = 13

5 +8 = 13

13 = 13

Cross-checked

Please help find the measurement of exterior angle MBI
boyakko [2]

Answer:

The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with  

N  sides.  It is equal to   360 o N .

Step-by-step explanation:  

Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.  

However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to  360 o .

It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of  

360 o . So, if all exterior angles are equal, like in a regular polygon, each one equals to  360 o N .

It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is  ( N − 2 ) ⋅ 180 o .  

Dividing the above by  N

we will obtain a value of an interior angle:  ( N − 2 ) ⋅ 180o N .  

Therefore, exterior angle of a regular polygon is  180 o − ( N − 2 ) ⋅ 180 o N = 360 o N
