Find the size of angle q if it is five times it's supplement​
tino4ka555 [31]

Answer:

<em>q =</em> 150

Step-by-step explanation:

Supplementary angles are angles that form a straight line and have a sum of 180 degrees, e.g. 120 and 60. If its supplement is thirty, and angle <em>q </em>is five times its supplement, it's 150. We know this is correct because 150 + 30 = 180, which is what we need for a supplementary angle.

Find all the missing dimensions when a=9, b=13, c=64°
DerKrebs [107]

Answer:

Part 1) c=12.14\ units

Part 2) m\angle A=41.78^o

Part 3) m\angle B=74.22^o

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

c^2=a^2+b^2-2(a)(b)cos(C)

we have

a=9\ units\\b=13\ units\\C=64^o

substitute

c^2=9^2+13^2-2(9)(13)cos(64^o)

c^2=81+169-234cos(64^o)

c^2=250-234cos(64^o)

c^2=147.4212

c=12.14\ units

step 2

Find the measure of angle A

Applying the law of sines

\frac{a}{sin(A)}=\frac{c}{sin(C)}

substitute the given values

\frac{9}{sin(A)}=\frac{12.14}{sin(64^o)}

solve for sin(A)

sin(A)=\frac{sin(64^o)}{12.14}(9)

sin(A)=0.6663

m\angle A=sin^{-1}(0.6663)=41.78^o

step 3

Find the measure of angle B

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle A+m\angle B+m\angle C=180^o

substitute the given values

41.78^o+m\angle B+64^o=180^o

m\angle B+105.78^o=180^o

m\angle B=180^o-105.78^o

m\angle B=74.22^o

20 Points--Algebra 1
Darina [25.2K]

Answer:

y = 400(1.01)^t

Step-by-step explanation:

Firstly find the rate

(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)

408.04-404= 4.04

I=(P*R*T)/100

From which R=(100*I)/PT

R= 100*4.04/404*1

R=1%

Using compound interest formula

A =P(1+r/100)^n

where n is time

substituting each value

y = 400(1+1/100)^t

y= 400(1.01)^t
