Answer:

x = 38, y = 4

Step-by-step explanation:

Since AB = BC  then the triangle is isosceles and the base angles are congruent, that is

∠ DAB = ∠ DCB = 52°

Subtract the sum of the base angle from 180° for ∠ ABC

∠ ABC = 180° - (52 + 52)° = 180° - 104° = 76°

Note that ∠ ABD = ∠ CBD, thus

x = 76 ÷ 2 = 38

BD bisects the side AC, thus DC = AD = 4

Thus y = 4

Answer:

45.2 × 10⁰ = 45.2 (a⁰ = 1 )

45.2 × 10¹ = 452

45.2 × 10² = 4520

45.2 × 10³ = 45200

According to the Americans with Disabilities Act, a ramp can rise no more than 1 ft for every 12 ft of horizontal distance. What
taurus [48]

Answer:

A. 4.8°

Step-by-step explanation:

We have that,

The horizontal distance for the ramp = 12 feet.

Maximum height of the ramp = 1 feet.

So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

\tan x=\frac{perpendicular}{base}

i.e. \tan x=\frac{1}{12}

i.e. \tan x=0.0833

i.e. x=\arctan 0.0833

i.e. x = 4.8°

Thus, the maximum angle made by the ramp with the ground is 4.8°.

What is LP ? <br><br> A. 36<br> B. 40<br> C. 44<br> D. 48<br> E. 52
Sonbull [250]

Answer:

The correct answer is option D.  48

Step-by-step explanation:

From the figure we can see that, some right angled triangles.

<u>To find the measure of LP</u>

Consider the right angled  triangle LPT,

LT is the hypotenuse, LP = 50 units  (given)

PT = QT = RT = 14 units

From figure we get,

LP² + PT² = LT²²

LP² = LT² - PT²

 = 50² - 14²

 = 2500 - 196

 = 2304

LP =√2304

 = 48

The correct answer is option D.  48
