Answer:

XY = 10 cm

Step-by-step explanation:

XY is a midsegment and is half the length of the 3rd side DE, that is

XY = $\frac{1}{2}$ DE = $\frac{1}{2}$ × 20 = 10 cm

Find logarithm of both sides

log (3^x) = log 8

xlog3 = log8

x = log8/log3

The diagram shows a regular polygon<br> What is the value of x?<br> How do I solve this

I am Lyosha [343]

Answer: x=120°

Step-by-step explanation:

What you are looking for is the value of the exterior angle of the regular polygon.

For a n-sided regular polygon, the external angle is given by the formula 360°/n.

Because the shape in this example is a regular triangle, the value of n is 3.

360°/n

=360°/3

=120°

Therefore, x=120°

This one is a tough one. If you can explain it to me that’ll me great.

Answer:

C. 73 if I have read the given angle measurements correctly.

The angle measurements I see are:

$219^\circ$

$(x-50)^\circ$

$(x+45)^\circ$ .

Step-by-step explanation:

Those angles together form a full rotation. A full rotation is equal to 360 degrees.

So we have the following equation to solve:

$219+(x-50)+(x+45)=360$

Combine like terms:

$(x+x)+(219-50+45)=360$

Simplify:

$2x+(219-5)=360$

$2x+214=360$

Divide both sides be 2:

$x+107=180$

Subtract 107 on both sides:

$x=180-107$

$x=73$
