Answer:

B. SAA (Side-Angle-Angle)

Step-by-step explanation:

In the diagram given, the horizontal sides of the two triangles are equal. Also, by the principle of opposite angles,

< RTS = < QTV

The two angles are equal.

Furthermore, the sum of angles in a triangle is $180^{0}$ , so the third angle can be determined since

< RST = < VQT = $90^{0}$

Thus the two triangles are congruent due to side - angle- angle.

Susan threw a softball 42 years on her first try and 51 1/3 yard on her second try. How much farther did she throw the softball

Andru [333]

Answer:

28 feet farther than 1st ball.

Step-by-step explanation:

We have been given that Susan threw a softball 42 yards on her first try and $51\frac{1}{3}$ yard on her second try.

To find second ball is how much farther from the 1st ball, we will subtract 42 yards from $51\frac{1}{3}$ yards.

$\text{The second ball is farther from 1st ball}=51\frac{1}{3}\text{ yards}-42\text{ yards}$

$\text{The second ball is farther from 1st ball}=\frac{154}{3}\text{ yards}-42\text{ yards}$

Let us have a common denominator.

$\text{The second ball is farther from 1st ball}=\frac{154}{3}\text{ yards}-\frac{42*3}{3}\text{ yards}$

$\text{The second ball is farther from 1st ball}=\frac{154}{3}\text{ yards}-\frac{126}{3}\text{ yards}$

$\text{The second ball is farther from 1st ball}=\frac{154-126}{3}\text{ yards}$

$\text{The second ball is farther from 1st ball}=\frac{28}{3}\text{ yards}$

$\text{1 yard}=3\text{ feet}$

$\frac{28}{3}\text{ yards}=\frac{28}{3}\times 3\text{ feet}$

$\frac{28}{3}\text{ yards}=28\text{ feet}$

Therefore, Susan thrown the second ball 28 feet farther from the 1st ball.

Answer:Area of the lawn is 1725 ft^2

Step-by-step explanation:

The yard is in the shape of a trapezoid. The area of the lawn can be determined by finding the area of the trapezoid. The formula for determining the area of a trapezoid is expressed as

Area of trapezoid =

1/2(a + b)h

Where

a is the length of one of the parallel sides of the trapezoid

b is the length of the other parallel side of the trapezoid.

h is the perpendicular height of the the trapezoid.

From the diagram,

a = 50 feet

b = 65 feet

h = 30 feet

Area of the lawn = 1/2(50 + 65)× 30

= 1/2 × 115 × 30 = 1725 ft^2
