Answer:

The area of the triangle = 31.5 feet² ⇒ answer (c)

Step-by-step explanation:

∵ Area of any Δ = 1/2 (side 1)(side 2)(sin the angle between them)

∴ The area of the Δ = 1/2 (b)(c) sin(∠A)

∵ b = 11 feet

∵ c = 10 feet

∵ m∠A = 35°

∴ Area of the Δ = 1/2 (11)(10) (sin(35)) = 31.547 feet²

∴ The area of the triangle = 31.5 feet²

∴ The answer is (c)

A 107-ft-tall building casts a shadow of 90 ft. To the nearest whole degree,

Paul [167]

Answer:

The answer is less than 50 degrees

explanation:

The solar elevation angle is the altitude of the Sun, the angle between the horizon and the centre of the Sun's disc. Since these two angles are complementary, the cosine of either one of them equals the sine of the other. They can both be calculated with the same formula, using results from spherical trigonometry.

Point A is located at (?5, 2) on a coordinate grid. Point A is translated 1 unit to the left and 5 units down to create point A'

svp [43]

ANSWER

C) 5.1 units

EXPLANATION

The coordinates of A are (5,2).

If this point is translated 1 unit to the left and 5 units down to create point A'.

Then A' has coordinates

$A(5,2)\rightarrow \: A'(5-1,2-5)$

$A(5,2)\rightarrow \: A'(4, - 3)$

The distance between A and A' is calculated using the distance formula,

$|AA'| = \sqrt{ {(5 - 4)}^{2} + {(2 - - 3}^{2} }$

$|AA'| = \sqrt{ {(1)}^{2} + {(5)}^{2} }$

$|AA'| = \sqrt{ 26}$

$|AA'| = 5.099$

We round to the nearest tenth to obtain,

$|AA'| =5.1 \: units$

The measurement that is closed to the distance is 5.1 units

Geometry/algebra stuff help

Neporo4naja [7]

Answer:

The answer to your question is: the second option is correct

Step-by-step explanation:

m∠1 = 180 - 66 - 37

= 77°

m∠2 = 180 - 41 - (180 - 77)

= 180 - 41 - 103

= 36°

m∠3 = 180 - 47 - (180 - 77)

= 180 - 47 - 103

= 30°
