Answer:
x=5
Step-by-step explanation:
Other than using the plain special aspect of a 45-45-90 triangle where the legs are x, x, and x√2, you can solve for this.
Since the two legs have equal length, they are both x. Using the pythagorean theorem:
(x^2)+(x^2)=50 (Because 5 squared is 25 and √2 squared is 2, multiplying them gives you 50).
You can add (x^2) and (x^2) because they are the same terms (x squared).
Simplifying like so gives you:
2x^2=50
Dividing by two on both sides:
x^2=25
Taking the square root of both sides:
x=5
Answer:
Step-by-step explanation:
No. of days Delynn played soccer = 3/5 of 45
= (3/5) * 45 = 3*45/5 = 3*9
= 27 days

Answer:
6/7
Step-by-step explanation:
Answer:
m = -3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
<em>m</em> = slope
<em>b</em> = y-intercept
We are given the equation y = -3x + 2. Therefore, our slope is -3 and our y-int is 2.
