Remark

I would have had the answer a whole lot sooner if I would have read the question properly. The figure in the circle is called a cyclic quadrilateral. It has the odd property that the angles that are opposite each other add up to 180o.

So DEB + DCB = 180o

DEB = 180 - 87

DEB = 93o

Note: The arcs marked 60 and 76 have nothing whatever to do with this problem.

if the length of a rectangle is increased by 30 percentage and the width of the same rectangle is decreased by 30 what is the af

LUCKY_DIMON [66]

Answer:

The area will decrease by 9%.

Step-by-step explanation:

The area of a rectange is given by the formula below.

$\boxed{\text{Area of rectangle}= \text{length}×\text{width}}$

Let the original length and width of the rectangle be L and W respectively.

Start by finding the original area:

Original dimensions

Length= L= 100%L

Width= W= 100%W

Original area= LW

Let's find the dimensions of the new rectangle in terms of L and W.

New dimensions

Length= (100% +30%)L= 130%L

Width= (100%-30%)W= 70%W

New area

$= \frac{130}{100} L \times \frac{70}{100} W$

$= \frac{91}{100} LW$

= 91% LW

Comparing the new area with the original area:

100% LW- 91% LW= 9% LW

∴ The area will decrease by 9%.

*Note that percentage is equivalent to dividing a number by 100.

A famous monument is 300 ft tall. When it casts 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall

Nataliya [291]

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets
