Sever21 [200]

Answer:

x=13

Step-by-step explanation:

set up the equation:

AXB+BXC=AXC

(2x+10)+(2x+10)=(6x-6)

What is the length of AA' , rounded to the nearest hundredth? Type a numerical answer is the space provided. Do not type spaces

inna [77]

Coordinate of A are (0,0)
Coordinates of A' are (5,2)

We can find the distance from A to A' using the distance formula:

$AA'= \sqrt{(5-0)^{2}+ (2-0)^{2} } \\ \\ 
AA'= \sqrt{25+4} \\ \\ 
AA'= \sqrt{29} \\ \\ 
AA'=5.39$

Thus, rounded to nearest hundredth, AA' is equal to 5.39

Given that Triangle ABC such that<br>a=8cm, b=7cm and c=9cm<br>tem and c= 9cm find Cos B

charle [14.2K]

Answer:

We use cosine rule also called cosine law which states

c^2=a^2+b^2-2abcosC

given

a=8cm, b=7cm, c=9cm cos C?

9^2=8^+7^2-2*8*7 cos C

expand

81=64+49-112 cos C

like terms together

81-113=-112 cos C

-32=-112cos C

multiply both sides by -1

32=112cos C

divide both sides by 112

32/112=cos C

cosC=0.2857

find cos inverse of 0.2857

angle C= 73.40
