I thinks the answer is 90 because the figure has. No sides and has an even number of triangles around it

Can someone show me the steps to doing this ?

U're goal is to get k alone.
So divide both sides by 9/10.
3/2 divided by 9/10 is 5/3

8.7/2=q/4 what is Q and give me work plez

ZanzabumX [31]

8.7/2=q/4
multiply both sides by 4: q=8.7/2*4
multiply both sides by 2: 2q=8.7 times 4
refine the equation: 2q=34.8
multiply both sides by 10: 20q=348
Divide both sides by 20: 20q/20=348/20
refine the equation for the final answer: q=87/5

Find the area of the figure. A-56cm^2 B-88cm^2 C-112cm^2 D-384cm^2

julia-pushkina [17]

firstly find the area of the square which is sidexside=8x8=64cm^2
then find the area of the triangle which is 1/2xbasexhight=1/2x8x6=24cm^2
THEN add both areas (64+24)=88cm^2

What is the relationship between sin(90 degrees) and sin(-90 degrees)

Volgvan

Answer:

$sin(90\°)=-sin(-90\°)$

Step-by-step explanation:

we know that

$sin(90\°)=1$

$sin(-90\°)=-1$

therefore

$sin(90\°)=-sin(-90\°)$
