Ksju [112]3 years ago

Answer:

A. x = 50

Step-by-step explanation:

x° + (x + 10)° + (x + 20)° = 180° (sum of interior angles of a triangle)

Solve for x

x + x + 10 + x + 20 = 180

Add like terms

x + x + x + 10 + 20 = 180

3x + 30 = 180

Subtract 30 from each side

3x + 30 - 30 = 180 - 30

3x = 150

Divide both sides by 3

3x/3 = 150/3

x = 50

Let the hypotenuse <span>of a 30-60-90 triangle = l
</span>So, the leg which faces angel 60 = l sin 60 = (√3)/2 l //  and the leg faces angel 30 = l sin 30 = 0.5 l  // 
∴ the longer leg = (√3)/2 l
∴ The ratio between the longer leg and hypotenuse =            (√3)/2 l : l  =              (√3)/2 : 1  =      √3 : 2  =       3 : 2√3
The correct choices will be C and E

What is the length of Line segment A C? 3 ft 4 ft 9 ft 18 ft
AfilCa [17]

Answer:

By the given diagram,

AM = MB and CN = NB

M and N are the mid points of the sides AB and CB respectively,

Thus, by the mid point theorem,

MN ║ AC,

By the alternative interior angle theorem,

∠BMN ≅ ∠BAC

∠BNM ≅ ∠BCA

Thus, by AA similarity postulate,

ΔBMN ≅ ΔBAC

By the property of similar triangles,

Thus, The length of AC is 18 ft.
