Theorem

The measure of an exterior angle of a triangle equals the sum of measures of the remote interior angles.

Angle STV is an exterior angle of triangle SRT.

The two remote interior angles to exterior angle STV are angles S and R.

Since the triangle is isosceles, with sides ST and TR equal, angles S and R are equal, so they both measure 27 deg.

<STV = 27 + 27

<STV = 54

Find the distance between A (6, -1) and B ( -18, 15)

timama [110]

Answer:

8√13 units

Step-by-step explanation:

We use the distance formula.

The distance formula states that the distance between two points (x, y) and (a, b) is equal to:

d = $\sqrt{(x-a)^2+(y-b)^2}$

Here, x = 6, y = -1, a = -18, and b = 15. Plug these in:

d = $\sqrt{(x-a)^2+(y-b)^2}$

d = $\sqrt{(6-(-18))^2+(-1-15)^2}=\sqrt{24^2+(-16)^2} =\sqrt{576 + 256} =\sqrt{832}$ = 8√13

The answer is thus 8√13 units.

Given: -2x < 10. Choose the solution set.

nadya68 [22]

Answer:

Step-by-step explanation:

given - 2x < 10 ( divide both sides by - 2 )

Remembering that the symbol is reversed when multiplying/ dividing by a negative quantity.

x > - 5 ← note reversal of symbol

solution is {x | x > - 5 } → C

What is the difference of (5 + 3i) and (2 + 9i)?

ehidna [41]

Answer:

3+12i

Step-by-step explanation:

The difference of 5+3i and 2 + 1999 can be calculated as follows

= 5+3i - 2+9i

Collect the like terms

= 5-2+3i+9i

= 3+12i

Hence the difference of 5+3i and 2+9i is 3+12i

Answer:

The second choice $(7.6,8.8)$

Step-by-step explanation:

The missing image is attached

We use the section formula:

$(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

We substitute $x_1=3,x_2=16,y_1=2,y_2=21$ and m=5, n=9

$(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})$

We simplify to get:

$(x,y)=(\frac{80+27}{14},\frac{105+10}{14})$

This simplifies to:

$(x,y)=(\frac{107}{14},\frac{125}{14})$

In decimals we get:

$(x,y)=(7.6,8.8)$
