Place the compass at one point and extend it halfway through the segment and draw an arc. Then use the same setting on the compass to draw another arc from point B. Then, use the ruler and the pencil to draw a line through the two points of intersection of the arcs. that is the perpendicular bisector. Hope this helps!

Answer:

x=π/2 ,3π/2

Step-by-step explanation:

cot x(csc x+1)=0

either cot x=0

tanx=∞=tan (π/2)

x=π/2

or csc x=-1

or sin x=-1=-sin (π/2)=sin (π+π/2)=sin (3π/2)

x=3π/2

a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169

Answer:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

Step-by-step explanation:

The formula for the area of a triangle is $\frac{1}{2} *b*h$

The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.

Since there are 2 of each triangles, we get:

$2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)$

The answer that fits is the first option.

After losing your job, and needing cash fast, you decide to try

ra1l [238]

Given:

The principal = $ 4000

The rate of interest = 22 %

To find the loan amount a) after 1 year and b) after 3 years.

Formula

Loan amount is

$A = P(1+\frac{r}{100} )^{t}$

where,

A be the loan amount

P be the principal

r be the rate of interest and

t be the time.

Now,

a) Taking, P = 4000, r = 22, t = 1 we get,

$A = 4000 (1+\frac{22}{100} )^{1}$

or, $A = 4880$

Again,

b) Taking, P = 4000, r = 22 and t = 4 w eget,

$A = 4000(1+\frac{22}{100})^{4}$

$or, A = 7263.39$

Hence,

a) The amount of loan after 1 year is $ 4880

and b) The amount of loan after 4 year is $ 7263.39.
