Answer:
Step-by-step explanation:
You have a 30-60-90 triangle. The sides of a 30-60-90 are in the ratio 1:√3:2.
The side opposite the 30° angle is 5, so the side opposite the 60° angle is 5√3, and the side opposite the 90° angle is 5×2 = 10.
x = 5√3
y = 10
Answer:
No
Step-by-step explanation:
They are not being added by the same number each time.
Answer:
Step-by-step explanation:
since 3 * 15 = 45, we know that we have to multiply 5 by 15. so the ratio would be 45:75. I hope this helps!
We have one of those equations already solved for y, so let's sub that one into the other one and solve the equation in terms of x only:
. We will simplify that and at the same time bring the 6 over by subtraction to get a polynomial set to equal 0 that we can factor.
. We will factor that to get (x-3)(x+1) for x values of x = 3 and x = -1. a above is the choice that has the x values we need, -1 and 3.
Answer:
The answer is 3111.
Step-by-step explanation:
You have to substitute the value of b and h in order to find A :
b = 61
h = 51
A = bh
A = 61×51
= 3111
