I need help with 5,6,7,and 8 please and thank you!!

Sergio [31]

Step-by-step explanation:

step 1. KITE is a kite

step 2. <ski + <kis + 90 = 180 (internal angles of a triangle has a sum of 180)

step 3. <ski + 25 = 90

step 4. <ski = 65°

step 5. <kes = <kis (angles across equal sides are equal)

step 6. <kes = 25°

step 7. <kie = <kis (they are the same angle)

step 8. <kie = 25°.

step 9. let's call ek = x and et = 1 5x

step 10. therefore x + 1.5x + x + 1.5x = 55

step 11. 5x = 55 or x = 11 = ek

step 12. et = 1.5x = 1.5(11) = 16.5.

Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3) explain and show all steps

spayn [35]

Simplification of (-2/5) divided by (8/9) times (2/9) divided by (-1/3) is 0.3

Solution:

Given that,

Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3)

Here "times" represent multiplication

The above sentence can be written mathematically as:

$\frac{-2}{5} \div \frac{8}{9} \times \frac{2}{9} \div \frac{-1}{3}$

Convert the problem to multiplication by changing the division sign to multiplication. When we change division sign to multiplication, the fraction becomes reciprocal

$\rightarrow \frac{-2}{5} \times \frac{9}{8} \times \frac{2}{9} \times \frac{3}{-1}$

Cancelling the common terms in numerator and denominator,

$\rightarrow \frac{-2}{5} \times \frac{1}{8} \times \frac{2}{1} \times \frac{3}{-1}$

Multiplying terms in numerator and denominator,

$\rightarrow \frac{-12}{-40}$

Negative sign in numerator and denominator cancels each other

$\rightarrow \frac{-12}{-40} = \frac{12}{40}$

Reducing to lowest terms we get,

$\rightarrow \frac{12}{40} = \frac{3}{10}$

In decimal form we get,

$\rightarrow \frac{3}{10} = 0.3$

Thus solution to given expression is 0.3
