Answer:

c = 7\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the left right triangle and the exact value

sin45° = \frac{\sqrt{2} }{2}, then

sin45° = \frac{opposite}{hypotenuse} = \frac{a}{7\sqrt{2} } = \frac{\sqrt{2} }{2} ( cross- multiply )

2a = 14 ( divide both sides by 2 )

a = 7

----------------------------------------------------------------

Using the tangent ratio in the right triangle and the exact value

tan30° = \frac{1}{\sqrt{3} } , then

tan30° = \frac{opposite}{adjacent} = \frac{a}{c} = \frac{7}{c} = \frac{1}{\sqrt{3} } ( cross- multiply )

c = 7\sqrt{3}

According to the synthetic division below, which of the following statements are true?
statuscvo [17]

A, D and E are correct

given ( x - 4 ) is a factor then x =  4 is a root

the remainder on division by (x - 4 ) = 0 as indicated by the 0 on the right side of the quotient

(x - 4 ) is a factor of 3x² - 13x + 4 → A

the number 4is a root of f(x) = 3x² - 13x + 4 → D ( explained above )

thus 3x² - 13x + 4 ÷ (x - 4 ) = 3x - 1 → E

the quotient line 3 - 1 0

3 and - 1 are the coefficients of the linear quotient and 0 is the remainder
