Thus, By the intersecting chord outside the circle theorem,

(x+5)\times 5=10\times 6

(x+5)\times 5=60

x+5=12

x =12-5

x =7

Hence, the value of x is 7.

In the right triangle below, tanA = 0.45. What is the approximate length of AB?
kodGreya [7K]

Answer with Step-by-step explanation:

We are given that:

tanA = 0.45

tanA= \dfrac{Perpendicular}{Base}

      =  \dfrac{BC}{AC}

⇒  \dfrac{BC}{AC}=0.45

⇒  \dfrac{9}{AC}=\dfrac{45}{100}

⇒  \dfrac{9}{AC}=\dfrac{9}{20}

⇒  AC= 20

Hence, by pythagoras theorem

AB²=AC²+BC²

AB²=20²+9²

AB²=481

⇒  AB=21.9 units

Hence,  the approximate length of AB is:

22 units

ok for the first one

the angle measurement of AE which is a straight line is 180

and the Angle measurement of ABC is 50 and because of vertical angles i know that the measurement of FBE is also 50 so all you do it

180 - 50 = 130

so you answer is C
