Find all the missing sides and angles of this triangle,

Mathematics
1 answer:
iren2701 [21]3 years ago
8 0

Answer:

See solutions below

Step-by-step explanation:

From the given diagram;

AC = opposite

AB = 7 = hypotenuse

Angle of elevation = 70 degrees

Using SOH CAH TOA

Sin theta = opp/hyp

Sin theta = AC/AB

Sin 70 = AC/7

AC = 7sin70

AC = 7(0.9397)

AC = 6.58

Similarly

tan 70 = AC/BC

tan 70 = 6.58/BC

BC = 6.58/tan70

BC = 6.58/2.7475

BC = 2.39

tan m<A = BC/AC

tanm<A = 2.39/6.58

tan m<A = 0.3632

m<A = 19.96degrees

Step-by-step explanation:

<h2><u>SIMPLE INTEREST </u></h2>

depreciates at a rate of 11% a year.

means it makes use of SIMPLE INTEREST!

simple interest formula is :

PRT / 100

where :

p is the principal

r is the rate on interest

t is the number of years.

(8000*11*5 ) / 100

=4400

Find the area of the shaded portion of the figure. Each vertex of square ABCD is at the center of a circle. Round your answer to
IrinaK [193]

<u>Given:</u>

Each circle has a diameter of 2 inches each.

The outer square has a side length of 4 inches and the square ABCD has a side length of 2 inches.

<u>To find:</u>

The area of the shaded region.

<u>Solution:</u>

Each circle has a diameter of 2 inches. The square ABCD is at the center of each circle so it has a side length of 1 inch.

To determine the area of the shaded region, we subtract the area of the quarter-circles in the square ABCD from the area of the square ABCD.

The area of a quarter-circle =\frac{\pi r^{2} }{4} .

All the quarter-circles have a radius of 1 inch.

The area of 1 quarter-circle =\frac{\pi r^{2} }{4} = \frac{\pi (1^{2}) }{4} = \frac{3.1415}{4} .

The area of 4 quarter-circles =4(\frac{3.1415}{4}) = 3.1415.

So the area of the quarter-circles in the square ABCD is 3.1514 square inches.

The area of a square = a^{2} .

The area of square ABCD =2^{2} =4.

The area of the shaded region =4-3.1415=0.8585.

The area of the shaded region is 0.8585 square inches.

What is the answer to 2x + 5= 19
Bogdan [553]
Rememer you can do anything to an equaiton as long as you do it to both sides

get x by itself

2x+5=19
minus 5 from both sides
2x+5-5=19-5
2x+0=14
2x=14
divide both sides by 2
2x/2=14/2
1x=7
x=7
