-2.3(4.5-3 1/2)<br> What is the answer

LUCKY_DIMON [66]

The computation shows that the value of the expression is 2.3.

<h3>How to illustrate the information?</h3>

It should be noted that the information given is illustrated as:

2.3(4.5-3 1/2)

This will be solved thus:

2.3(4.5-3 1/2)

2.3 ( 4.5 - 3.5)

= 2.3 (1)

= 2.3 × 1

= 2.3

Therefore, the value is 2.3

What is the area of triangle PQR? Round to the nearest tenth of a square unit.

larisa86 [58]

ANSWER

111.3 square units.

EXPLANATION

The formula for calculating the area of a triangle is.

$Area = \frac{1}{2} \times base \times height$
Let us the side of the triangle with side 12 units to be the base of the triangle.

Then the height of the triangle can be determined from the diagram using trigonometry.

$\sin(68 \degree) = \frac{height}{20 }$

$height = 20 \sin(68 \degree)$

$height = 18.54$

We now plug in the values in to the formula to obtain,

$Area = \frac{1}{2} \times 12 \times 18.54$

$Area = 111.3 \: square \: units$
