5^2+10^2=125+100=225 Square root of 225= 15 the answer is 15
Answer: cos y°=t divided by 8
Step-by-step explanation:
Given the following :
tan y° = s / t
sin y° = s / 8
Using Pythagoras rule ;
sin y° = opposite / hypotenus = s / 8
tan y° = opposite / Adjacent = s / t
Therefore,
cos y° = Adjacent / Hypotenus
Cos y° = t / 8
Answer:
True similar triangles don't have to be the same size
Step-by-step explanation:
Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
