Ahat [919]

Answer:

Consecutive sides must be congruent.

All interior angle adds up to 360°

Step-by-step explanation:

Rhombus:

1. Sides: all 4 sides are congruent.

Then consecutive sides must be congruent.

2.Diagonals : Diagonals bisect each other at 90°.

So, second option is wrong.

3. Sum of interior angle is 360°.

3-^1 x (4 x 6) x 2-^3

xeze [42]

$\huge{ \boxed{ \mathbf{ \blue{Problem:-}}}}$

$\bold{ {3}^{ - 1 \ } (4 \times 6) \times {2}^{ - 3} }$

$\huge{ \boxed{ \bf{ \blue{Solution:-}}}}$

$\bold{ {3}^{ - 1}(4 \times 6) \times {2}^{ - 3} }$

$= \bold{ \frac{1}{3}^{1} (4 \times 6) \times { \frac{1}{2}^{3} } }$

$= \bold{ \frac{1}{3} \times 24 \times \frac{1}{8} }$

$\bold{= 1}$

If tan (theta) =5/4 and cos (theta) < 0 . Find the other trig. functions.

andrew-mc [135]

Tan(theta) = 5/4
sin(theta)/cos (theta)=5/4
cos(theta)=4sin(theta)/5
sin²(theta)+cos²(theta)=1
sin²(theta)+16sin²(iheta)/25=1 /*25
25 sin²(theta)+16 sin²(theta)=25
sin²(theta)=25/41 /√
sin(theta)= $\frac{-5 \sqrt{41} }{41}$
cos(theta)= $\frac{-4 \sqrt{41} }{41}$
cot(theta)= $\frac{4}{5}$
csc(theta)=1/sin(theta)= $\frac{- \sqrt{41} }{5}$
sec(theta)=1/cos(theta)= $\frac{- \sqrt{41} }{4}$
