Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths

the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths

Find BC. Round to the nearest tenth
SSSSS [86.1K]
<span>Using LAW OF SINES Round to the nearest tenth. 
Find BC: triangle is laying on it's side with the point to the right point(A).

B to C= 61 degrees
C to A= 23 cm
A to B= 12 degrees
--------------------
If I interpret this correctly:
Angle A = 61º

Angle C = 12º
--> B = 103º
-------------
Side b = 23 cm
--------------
BC is side a, opposite angle A
--------------
23/sin(103) = a/sin(61)
a = 23*sin(61)/sin(103)
a =~ 20.6 cm 

Hope this helped :)</span>

Below is a Venn Diagram.

Answer:

A = 8, B = 9 and C = 6.

Step-by-step explanation:

We can create equations to solve this:

6 + A = 14

So A = 8.

A + B = 17

8 + B = 17

B = 9.

C = 29 - (6 + A + B)

= 29 - ( 6 + 8 + 9)

= 29 - 23

= 6.

X +3/ 5 = 2 <br> i need help
DochEvi [55]

This equation basically says that a number plus 3/5 equals 2 so we can simply:

2 - 3/5 = x

Therefore x equals 1 & 2/5 or 1.4

PLEASE HELP!! I'LL MARK BRAINLIEST &amp; 30 POINTS
ser-zykov [4K]

We are first ask to translate this equation. So using the correct notation...

3X-9=6x6/4

We can also solve it.

3x-9 = 6x6/4

3x-9 = 36/4

3x-9 = 9

3x = 18

x=6

answer: X=6
