The base of a triangle is 5?45 cm and the height is 3?88 cm. What is the area of the triangle? Recall: A= 1/2bh

Angelina_Jolie [31]

Answer:

10.57 cm²

Step-by-step explanation:

Recall that the area of a triangle is gotten by (1/2)*base*height

If the height of the triangle is 5.45cm and the base is 3.88cm, then the area can be calculated by multiplying the two numbers and dividing it by 2.

5.45*3.88 = 21.146cm²

This still needs to be cut in half (otherwise we are yielding the area of a rectangle with these dimensions)

21.146 cm²/2 = 10.573 cm²

This can be rounded to the nearest hundredth

= 10.57 cm²

Answer:

A. 871.97 m

Step-by-step explanation:

Model this is a <u>right triangle</u>.

Use the <u>sine trigonometric ratio</u> to find the height of the weather balloon from the ground.

<u>Sine trigonometric ratio</u>

$\sf \sin(\theta)=\dfrac{O}{H}$

where:

$\theta$ is the angle
O is the side opposite the angle
H is the hypotenuse (the side opposite the right angle)

Given:

$\theta$ = 33°
O = height
H = 1601 m

Substitute the given values into the formula and solve for O:

$\implies \sf \sin(33^{\circ})=\dfrac{height}{1601}$

$\implies \sf height=1601\sin(33^{\circ})$

$\implies \sf height=871.97\:m\:\:(nearest\:hundredth)$
