Answer:
x = y = 15
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
2x = 30 ( divide both sides by 2 )
x = 15
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15
x=10
Step-by-step explanation:
10 times -4 is -40 since if you multiply a negative number by a positive you get a negative
Each variable used is the first letter of each of their names.
t+b+c=87
c=2t
b=t+7
Substitute for b and c
t+ (t+7)+2t= 87
4t+7=87
4t=80
t=20
Plug in the known t value.
c=2(20)
c=40
b=20+7
b=27
Final answer: Tammy=$20, Boris= $27, Carlos=$40
Answer:
2
Step-by-step explanation:
Divide both sides by -5
You would then get (square root)x=3 since the negatives would cancel out
Then you square both sides
You will be left with (x)*2=(3)*2
Your answer will be C. X=9
Hope that helped!
