Answer:

U and S are congruent and sum of 4 angles is 360.

130 + 2*80 + m∠T = 360
m∠T = 360 - 290
m∠T = 70

Correct choice is B

∠1 and ∠3 are complementary, AC is angle bisector and ∠2 is right angle since diagonals of a kite are perpendicular

∠DAC≅∠BAC
m∠1 = 39°
m∠3 = 90° - 39° = 51°

Correct choice is C

A- guaranteed
B- guaranteed
C- guaranteed
D- not guaranteed as it could be a rhombus

If 16 is added to one-third of a number, the result is three times the number. What is the number?

AnnZ [28]

First set up the equation based on the description.

$\frac{1}{3}$ x + 16 = 3x

Use subtraction to get the "x"s on one side of the equation. You can next subtract <span> $\frac{1}{3}$ x from both sides.

16 = </span> $\frac{8}{3}$ <span> x

Now you can multiply both sides of the equation by </span> $\frac{3}{8}$ <span> to solve for x

x = 6</span>

I need help with this... I don't understand geometry at all lol.

1. vertical angle theorem and triangle angle sum theorem

2. The sum of the interior angles of a triangle = 180
so < x = 180 - (70 + 30) = 180 - 100 = 80
and < y is a vertical angle to < x...and vertical angles are equal..
so < y = 80
